Naval  Consulting  Board  and  Related  Wartime  Research  Papers 
Correspondence  (1918) 

These  folders  contain  correspondence  and  other  documents  relating  to 
Edison's  role  as  president  of  the  Naval  Consulting  Board  (NCB),  as  well  as  to 
his  personal  research  for  the  U.S.  Navy  during  the  final  year  of  World  War  . 
The  correspondents  include  Secretary  of  the  Navy  Josephus  Daniels,  J. 
Jarvis  Butler  and  W.  Strother  Smith  of  the  Navy  Dept.;  NCB  chairman  Wil  iam 
L  Saunders  and  secretary  Thomas  Robins;  Andrew  M.  Hunt  of  the  U.S. 
Shipping  Board's  Ship  Protection  Committee;  and  members  of  Edison  s  staff 
including  his  personal  assistant  William  H.  Meadowcroft,  chief  engineer  M Her 
Reese  Hutchison,  and  experimenters  Bruce  R.  Silver  at  Jones  P°int.  New 
York,  and  Samuel  C.  Shaffner  at  Key  West,  Florida.  Other  correspondents 
include  Harvey  S.  Firestone,  Peter  Cooper  Hewitt,  and  officials  of  the  Black 
Diamond  Powder  Co.,  the  Ford  Motor  Co.,  and  the  Italian  government. 

Many  of  the  documents  relate  to  Edison's  stay  at  the  naval  base  in  Key 
West  during  February-April  1918.  The  subjects  covered  include  research 
arrangements,  facilities,  staffing,  expenses,  equipment  and  supplies,  and  the  . 
use  of  the  USS  Sachem.  There  are  also  items  concerning  Edison  s  plan  to 
trade  coal  for  Cuban  sugar,  the  development  of  a  hydrogen  detector  by 
Selden  G.  Warner,  tests  of  sea  anchors  for  the  rapid  turning  of  ships,  and 
work  on  smoke  bombs  and  incendiary  devices  In  addition,  there  are 
documents  regarding  the  disagreement  among  Edison  and  oth®  NCB 
members,  including  David  W.  Brunton,  Frank  J.  Sprague,  and  WiM's  R. 
Whitney,  about  the  site  for  a  Naval  Research  Laboratory.  Other  'ettersdeal 
with  the  need  for  antisubmarine  research  and  a  visit  to  the  National  Research 
Council's  experimental  station  at  New  London,  Connecticut,  the  leading  site 
for  such  work.  There  are  also  a  few  letters  discussing  Edison  s  views  at  the 
end  of  the  war.  Several  documents  mention  the  need  to 'reschedule  NCB 
meetings  as  a  result  of  the  outbreak  of  Spanish  influenza.  Among  the  Edison 
experimenters  represented  in  the  documents  are  William  Deans,  Charles  B. 
Hanford,  John  A.  Hanley,  Newman  H.  Holland,  Paul  D.  Payne,  and  Henry  G. 

Approximately  30  percent  of  the  documents  have  been  seiected.  The 
unselected  material  includes  unsolicited  offers,  requests  and  submissions 
most  of  which  received  a  brief  form  reply  .  Other  unselected  documents 
include  letters  of  transmittal  and  acknowledgment,  routine  interoffice 

communications,  Meadowcroft's  personal  correspondence;  and  test  reports, 
technical  documents,  and  other  items  pertaining  to  research  projects  not 
directly  related  to  Edison.  Also  not  selected  are  routine  administrative 
correspondence  regarding  military  service  of  personnel  and  documents 
concerning  the  production  of  war  equipment  by  Thomas  A.  Edison,  Inc.

Dear  Ur.  silver: 

I  am  in  receipt  of  your  favor  of  the 
31et  ultimo,  enclosine:  copies  of  your  correspondence 
with  Ur.  G.  A.  Kichtor  of  the  Bureau  of  nines  Jirpori- 
mont  Station,  in  regard  to  Oleum. 

Inasmuch  as  your  druiaof  Oleum  has  not  yet 
arrived,  we  cannot  lot  either  Ur.  Richter  or  Ur.  Clark 
have  any.  You  certainly  cannot  spare  any  out  of  the 
small  stock  which  you  hnvo  at  present.  ^s  the  Boat 
is  going  away  so  soon,  tho  problem  will  be  solved,  as 
you  cannot  lot  them  have  the  Oleum  if .  you  aro  not  there. 

I  have  callod  up  tho  Gonoral  Chemical  Co. 
again  this  afternnon  to  ask  thorn  if  they  had  any  returns 
from  the  telegraph  tracer.  Shoysay  they  havo.  not.  . 
but  will  push  it  all  it  is  possible.  Railroad  affairs 
aro  in  a  chaotic  otuto  at  nrocont,  and  it  is  practically 
impossible  to  got  any  action  on  tracors.  .  She  Conoral 
Chemical  Co.  told  mo  that  tho  Southorn  Railway  Company 
hiiB  closed  most  oiV  i*ts  oi'ficos  Gnd  will  not  uckc  uri^ 
action  vrhatevor  on  tracers.  .This  obtains  also  in 
many  other  Railway  Companion. 

Ur.  Edison  wont  back  to  Washington  this  after¬ 
noon,  and  boforc  going  ho  asked  mo  to  euy  to  you  that 
you  ought  to  huvo  a  supply  of  tho  "boat  fuse  ropo".  nave 
you  got  -plonty  of  it?  ’  If  not,  pleaBO  telograph  mo  to¬ 
morrow  whore  and  how  much  to  ordor,  and  givo  description. 
At  tho  samo  time,  ploaso  cuyyhon  you  oxpoct  to  got

Hy  dear  3haf fner : 

Ur.  Edison  has  taken  ike  Congressional 
limited  this  afternoon.  Before  he  left  he  ashed  me  to 
write  and  say  to  yon  that  you  ought  to  have  several  extra 
Bell  'phones.  lie  requested  mo  to  ask  whether  you  had  a 
half-do  son. extra  ones.  If  not,  please  let  me  know  by  wire 
tomorrow  and  I  Will  order  them.  Please  give  me  the  number 
or  other  trade-name  so  that  I  can  get  the  right  ones. 

The  hailway  situation  has  grown  to  be  very  bad, 
indeed,  and  it  may  effect  your  receiving  materials  for  a 
while.  One  of  the  Express  Companies  has  just  notified 
us  that  they  requested  their  Drives  s  not  to  pick  up  any¬ 
more  Express  matter  until  further  notice.  2ki6  will  be 
undoubtedly  followed  by  others. 

1  received  your  note  this  morning  on  my  desk, 
and  will  attend  to  the  matters  noted.  I  am  afraid  that 
I  have  appeared  awfully  stupid  to  you  in  repaid  to  the  ear 
tubes,  but  the  boys  have  used  so  many  different  kinds  of 
things  I  was  not  sure  and  wanton  to  bo  certain  about  thorn.

January  3,  1917 

Mr.  Thomas  A.  Edison, 

Washington,  D.C. 

Dear  Mr.  Edison: 

The  following  is  quoted  from  Secretary  Daniels' 
report  for  1917  >  ps-68  71* 

"With  war  conditions  increasing  the 
need  for  labor  and  building  materials, 
it  was  believed  to  be  a  wise  policy  to 
defer  for  a  time  the  building  of  the 
new  experimental  and  research  labora¬ 
tory.  Such  experiments  as  have  been 
warranted  have  been  made  in  private 
laboratories  generously  offered  and  at 
the  Bureau  of  Standards.  The  need 
for  this  establishment,  however,  is 
more  clearly  shown  than  ever,  and  its 
support  is  urgently  advised." 

If  the  support  of  such  a  laboratory  is  urgently 
advised,  we  certainly  cannot  do  better  than  lend  some  aid. 
While  the  bureaus  of  the  Government  are  doing  some  of  the 
work  of  the  Navy,  there  is  much  of  it  left  undone  and  much 
of  it  is  being  done  by  private  capital.  It  is  highly 
probable  that,  if  a  site  is  not  chosen  before  the  war  is 
over.  Congress  will  feel  itself  justified  in  not  permitting 
new  expense  at  a  time  when  the  Government  indebtedness  will 
be  the  greatest  in  its  history. 

If  we  decide  on  a  site,  it  can  certainly  be 
purchased,  even  tho  some  of  the  buildings  could  not  be 
economically  ereoted  at  present. 

There  has  been  started  at  New  London  a  plant 
whioh  is  already  much  nearer  to  being  a  Navy  research 
laboratory  than  we  have  yet  created,  and  it  has  grown 
and  is  growing  like  Topsy. .  That  is  probably  not  the 
best  place  for  a  laboratory,  and,  so  far  as  we  know,  no 
plans  have  been  developed  for  carrying  out  at  New  London 
much  of  the  v/ork  which  a  Navy  laboratory  ought  to  do. 

The  experience  there  shows,  however,  how  easily  a  thing 
of  that  kind  cam  grow  under  war  conditions;.  In  spite 
of  the  cold  weather  and  the  ice  in  the  river,  they  are 
drawing  submarine  chasers  up  on  the  shore  at  this  plant 
and  installing  thru  the  bottom  and  on  the  sides,  various 
experimental  devices.  This  work  could  be  done  with  much 
greater  efficiency  in  warmer  climates.  We  think  it  is 
safe  to  say  that  there  will  be  involved  several  hundred 
boats,  witha  great  many  experiments  apiece,  before  this 
class  of  work  is  complete,  if  it  ever  is,  and  this  is  only 
a  very  small  part  of  the  experimental  work  we  ought  to  be 
doing.  We  ought  to  have  a  place  where  we  could  install 
a  complete  boiler  system  in  an  imitation  boat  hull  on  land, 
with  powdered  coal -making  plant,  for  fuel  tests. 

It  is 

I.A.E.  -  3 

not  fair  to  ask  tho  Shipping  Board  to  install  a  new  out¬ 
fit  which  has  not  been  given  adequate  test  on  a  boat. 

Vie  could  simulate  a  boat's  body,  test  such  a  device,  and 
show  the  results  a3  easily  as  by  laying  up  a  suitable 

This  powdered  coal  suggestion  is  only  one  of 
a  number  of  the  same  kind  of  experiments  -  experiments 
entirely  unsuited  for  the  Bureau  of  Standards  or  even 
the  Bureau  of  Mines  to  carry  out.  Take,  for  example, 
storage  battery  testing  in  general.  The  scarcity  of 
submarines  makes  it  almost  imperative  to  build  an  imi¬ 
tation  submarine  on  shore  and  oarry  out  the  operations 
of  the  battery  in  a  space  with  the  dimensions  and  nature 
of  the  submarine,  and  to  build  there  the  suggested  exper¬ 
imental  devices  for  removal  of  gases  or  practical  test  of 

In  studying  the  driving  engine  for  chasers  and 
submarines,  we  have  unearthed  two  new  oil  engines  which 
ought  to  be  built  at  once  and  tested  under  the  requirements 
of  chasers  and  submarines.  One  of  these  was  designed  by 
Commander  Fisher,  of  the  Navy.  Facilities  for  this  work 
must  now  be  sought  in  the  industrial  plants  of  the  country, 
tho  this  type  of  work,  limited  in  application  to  the  Navy's 
needs,  should  be  carried  out  in  its  own  shops.  A  simple 
low  pressure  engine,  using  the  standard  boiler  tfftel;.bil,  has 

shown  members  of  the  Board  the  apparent  possibility  of 
an  engine  with  practical  Diesel  engine  efficiency,  but 
with  much  greater  simplicity,  and  we  are  at  a  loss  at 
present  to  know  how  to  recommend  the  suitable  making 
and  testing  of  a  complete  engine. 

In  cases  like  the  laboratory  site,  it  is  often 
true  that  any;  one  of  a  number  is  better  than  no  choice. 

A  factory  fitted  solely  for  producing  submarines,  capable 
of  turning  one  out  in  a  few  weeks  and  located  anywhere  in 
the  United  States,  would  be  a  todm  better  laboratory  propo¬ 
sition  than  anything  we  have  produced  as  a  Naval  Board, 
and  for  that  reason,  among  others,  we  have  been  anxious 
to  express  preference  for  any  site  with  unanimity. 

The  fact  that  the  severity  of  the  winter  climate 
is  greatly  crippling  the  work  at  Nahant  and  New  London  and 
has  forced  us  to  send  some  men  south  for  experimental  work, 
makes  it  seem  as  the  the  suggested  site  on  the  Potomac  River 
possesses  a  number  of  practical  advantages.  As  the  entire 
Board  would  be  willing  to  agree  on  recommending  this  site, 
if  you  will  do  so,  we  were  requested  to  ask  you  if  you  would 
consider  it. 

Yours  very  truly, 

January  b, 1910. 

Doar  Ur.  Shaf  frier:  ' 

■  I  was  notified  ovor  the  telophono  this' morning 
that  tho  Volt  Ammo ter  was  repaired  and  roaav  for  delivery,  to  i 
have  Bont  a  man  ovor  for  it.  _ 

Yesterday  1  sent  you  by  Parcel  font  two  of  tho  oar  tubes, 
ouch  as  were  shown  in  your  sketch  sent  to  mo  a  fev.  days  ugo .  X 
trust  these  will  bo  received  in  good  condition. 

/Please  do  not  think  that  I  overlooked  your  request  for 
\30mc  laboratory  lottorhoads  and  onvolopos.  X  rogrot  to  disappoint 
you  about  this,  but  it  is  a  vory  stringent  rule  laid  down  by  i-r. 
Edison  that  our  .labor-  tooy  -lottorhoads  and  cnvolopee  shall  not  bo 
used  oxcopt  right  at  tho  laborator;  ,  and  ho  never  allov.s  us  to 
givo  any  of  them  out.  Even  v.hon  I  was  down  with  him  in  Washing 

ton,  I  did  not  carry  any  laboratory  letterheads.  If  it  was  do- 
-  oil-able  to  write  an  official  lot.or,  I  drafted  it  and  sont  it  up 
here  to  the  laboratory  to  be  typewritten  on  our  letterheads  and 
forwarded  to  me  for  lir.  Edison  for  signature  in  most  cases. 

If  at  any  timo  there  is  a  special  reason  why  it  would  b'o  bettor 
to  write  any  particular  letter  on  the  laboratory  letterhead,  you 
can  draft  it  up  and  sond  it  hore.  and  I  will  have  it  typowritton 
for  you.  ’  i  . 

1  have  roeeivod  a  tologram  from  lir.  Silver  stotinc  that 
you  ere  .fror.on  in  ana  will  go  out  at  tho  first  opportunity,  it 
i 3  (pile  important  for  no  to  have  an  approximate  .idea,  if  pocsiblo, 
when  you  will  got  out,  because  I  am  collecting  u'loVof  supplies 
which  Ur.  Edison  has  specially  ordored .  .  Sheco  will  all  bo 

ready  to  ship  by  Express  on  Uondsy  noxt,  tho  7th  instant.  If 
it  v:131  bo  two  or  tliroo  days  beforo  you  will  be  able  to  get  out, 
pleaso  telegraph  mo  first  thing  Holiday,  and  1  will  make  special 
arrangements  with  tho  Express  Col  to  put  them  right  through  so  as 
to  catch  yb'u  in  Annapolis.  If  thorn  is  a  reasonable  prospoct 
that  you  will  go  away  bofore  Wednesday  night,  please  lot  rao  know, 
as  I  would  then  ship  all  tho  things  to  iloy  West.- 

With  kindest  fcgards_to  you  all,  I  remain.

FICE  OF  THE  PRESIDENT  January  7,  1918. 

Thomas  A.  Edison,  Esquire, 

Room  502,  U.  S.  Navy  Annex, 

Washington,  D.C. 

My  dear  Mr.  Edison: 

Permit  me  hy  this  letter  to  introduce 
to  you  Mr.  Daniel  M.  Wise,  one  of  the  engineers  of  our 
Department  of  Terrestrial  Magnetism,  who  has  been  assign¬ 
ed  to  assist  you  in  the  computing  you  contemplate.  He 
is  a  man  of  unquestioned  loyalty  to  the  U.  S.  Government 
and  I  think  he  will  he  able  to  give  you  the  assistance 
desired.  In  case  some  special  additional  work  to  that 
contemplated  arises,  he  will  probably  be  able  to  draw 
on  his  colleagues  in  the  Department  of  Terrestrial  Mag¬ 
netism  for  any  service  or  information  that  may  be  avail¬ 
able  in  the  Department. 

I  need  hardly  add  that  the  services  of  Mr.  Wise 
will  be  given  gratuitously. 

Faithfully  yours.

The  Francis-Rosencrantz  Multishot  Gun  Magazine 

Through  the  courteous  suggestion  of 
Mr.  .T.  Pierpont  Morgan  that  I  official  '"nshi ngton 
of  an  improvement  of  vast  importance  to  the  modern  small 
firearm,  I  hep  to  submit  to  your  serious  consideration 
a  pun  magazine  that  doubles  the  cartridge  capacity  of 
any  standard  mun  in  the  world  today  without  enlarging  the 
dimensions  of  the  gun.  I  know  this  appears  incredible 
but  this  claim  can  be  proven  by  producing  a  regulation 
stock  pun  using  this  magazine  that  will  fire  double  the 
gun's  usual  capacity  with  the  same  caliber  bullet. 

Now,  Mr.  Edison ,  I  trust  it  will  he 
your  pleasure  to  •’•rant  me  an  immediate  authorization  to 
present  this  matter  to  the  proper  authorities. 

Assuring  you  of  my  deep  appreciation  for 
your  kind  attention  pivon  this  letter, 

Yours  most  respectfully^/'

Mr.  S.  C.  Shaffnor, 

c/o  Thomas  A.  Edison  laboratory, 

Orango,  H.  J. 

My  Dear  Mr.  Shaffnor : - 

Your  favor  of  the  4th  inst.,  received 
and  am  pleased  to  advise  that  wo  would  he  able  to  me he 
up  a  cable  such  as  you  suggest  with  an  insulated  steel 
center  and  surrounded  with  wires  separated  in  such  a 
way  as  to  give  three  or  four  separate  conductors  on  the 
outside.  This  could  be  again  insulated  so  as  to  be 
about  the  same  diameter  as  the  cable  which  w o  have  just 
shipped  you,  and  I  think  could  easily  carry  throe  or 
four  curronts  on  this  cable. 

When  we  made  up  tho  first  lot  of  cables  for 
you,  we  made  three  cables,  two  of  which  wo  shipped  with 
the  btoe-  rubbor  on  the  o\itside,  tho  other  coble  we  heve 
briided  with  a  hard  finish  fine  cotton,  and  are_  having 
same  covored  with  varnish.  I  thought  it  might  be  well 
for  you  to  try  this  out,  as  it  is  quite  possible  that 
it  will  draw  through  tho  water  easier  than  what  we  furn¬ 
ished.  This  cable  will  be  ready  tomorrow  and  I  would 
like  very  much  if  you  would  advise  me  whore  to  ship  it. 

Hoping  for  an  early  reply,  I  bog  to  remain, 

Yours  very  truly, 


Vico  President.

I  am  sending  you  aJLg.|f*er  4^ 
which  I  had  sent  to  Mr.  Jh^nders ,  thinking  that^ha^ 
and  Mr.  Hewitt  might  be  willing  to  indorse  it  a.x\Ar 
bring  it  to  you  last  Saturday.  I  was  unable(to  be 
in  Washington  that  day.  Apparently  this  letter 
reached  Mr.  Saunders  too  late  for  him  to  make  use 
ox  it,  but  he  suggests  that  I  sena  it  to  you  as  a 
personal  letter,  which  I  hereby  do.

In  reply  to  your  nenoranoun:  of  January  e?,  sucndttir.^^- 
particulars  of  a  multiple  drill  press,  invented  'ey  iTr.  Aaron 
Hill,  I  wish  to  thank  you  for  calling  This  natter  to  ay 

It  appears  that  this  press  should  he  very  useful 

three  large  fabricating  yards,  giving  then  the  information, 
and  suggesting  that  they  go  into  the  natter  further  with  Hr. 

It  does  not  appear  practicable  for  the  Fleet  Corpo¬ 
ration  to  undertake  the  manufacture  of  this  drill  press,  as  it 
is  a  natter  that  can  better  be  handled  by  the  shipyards 

themselves .

Mr.  Thome  JS.  Edison, 

Room  502,  Hqvy  Annex, 

Washington,  D.C. 

My  dear  Mr.  Edison  : 

After  looking  this  whole  situation  ober 
with  Commandant  Traut,  and  at  hi 8  suggestion,  I  write 
t1  following  facts  : 

This  Havy  Yard,  containing  about  21  acres 
on  the  edge  of  the  city,  is  a  "beauty  spot”  with  palms, 
flowers,  walks  and  well  kept  buildings.  On  the  oity  side 
of  the  Yard  is  a  high  iron  fonoe  with  two  gates,  well 
guarded  by  Marines.  Ho  one  is  allowed  inside  but  Govern¬ 
ment  people,  leaving  the  whole  Yard  free  to  move  in,  in 

On  the  other  side  of  the  Yard  are  fine 
wharves  with  deep  water  all  private  and  within  the  Yard 

They  have  a  fine  machine  shop  with  lathes, 
shapers,  planers,  drills,  grinders,  small  tools  and  ap¬ 
parently  ten  or  fifteen  good  machinists.  A  good  foundry 
with  several  molders.  A  wood  working  shop  with  tools, 
machines  and  Btook  of  material..  They  have  a  stock  of 
material  uuoh  as  rods,  tubes,  slieetB  of  various  sizeB 
and  thicknesses.  In  fact  it  looks  like  thoy  have  every¬ 
thing  anyone  could  ask  for  in  the  metal  and  wood  lineB. 

Commandant  Sraut  lives  in  a  beautiful  home 
within  this  exclusive  enclosure ,  an  ideal  family  and  home . 

the  ui 

The  docks  ero  ideal  and  through  his  ef- 
/o  have  arranged  with  the  Lighthouse  Dep’t  (in  the 
of  the  docks  ana  yard)  a  Blip  to  put  our  boat,  and 
,  of  a  part  of  their  warehouse  to  store  our  unused 

or  surplus  material . 

They  have  a  good  fort  and  grounds  praoti- 
oally  on  the  grounds  whioh  oan  be  used  for  any  purpose  you 
may  want. 

Commandant  Traut  suggests  that  you  oould  get 
the  use  of  the  lighthouse  tend of  a  good  part  of  each 
month  if  you  needed  it,  or  some  of  the  smaller  ones. 
Several  of  the  larger  government  ships  are  in  here  (I 
don't  think  it  prudent  to  describe  in  writing;. 

What  I  haa  in  mind  was  tha  t  if  the  Sachem  is 
still  tied  up  and  you  want  to'  ship  the  material  from  it 
down  hero  and  oome  on  down,  I  am  sure  you  can  work  all 
vour  work  here  at  onoo  with  the  boats  and  otner  facil¬ 
ities  here.  The  weather,  land  and  water  conditions  are 
ideal  here. 

The  Reposo  II  wired  they  had  to  stop  Saturday 
at  Brunswick,  Ga.  on  account  of  a  severe  storm.  Expect 
them  tonight  or  tomorrow. 

Commandant  Traut  aBked  the  diameter  and  other 
dimensions  of  the  brotherhood  torpedoes  you  ezpect  to 
ship  here,  so  he  can  soe  if  he  has  a  boat  with  the  prop¬ 
er  siae  tube. 

Very  respectfully.

Havy  Yard, 

Key  West,  Fla. 

My  a ear  Mr.  Shaffner: 

Just  a  line  to  let  you  know  that  your  various 
requirements  are  receiving  attention.  Up  to  date,  your  unfilled 
orders  are  as  follows: 

1  Spool  Ho.  36  S.S. Covered  Cable  Wire; 

6  Gal.  Solution  for  replenishing  Storage 
Batteries ; 

2  Hand  telephones  200  Ohms; 

4  »  »  80  " 

4  Pieces  of  best  magnet  steel,  l/4"  by 
3/4"  by  8  inches  long. 

They  dia  not  have  any  3/4"  width,  and  the  only 
thing  I  could  get  was  l/l/4"  instead  of  3/4"  measurement.  You 
will8simply  have  to  have  it  cut  to  size  with  a  metal  saw .which 
they  will  probably  have  in  the  Machine  Shop  in  the  liavy  Yard. 

All  these  orders  are  receiving  attention,  ana  we 
shall  begin  to  make  shipments  in  a  few  days.  We  couia  not  get  them 

I  trust  the  Voltammeter  reached  you  in  good  order, 
and  also  that  the  Boat  made  a  good  trip  down  to  Key  West. 

With  kind  regards  to  you  and  the  boys,  1  remain,

that  you  had  hotter  put  it  up  to  tho  ..meriean  University  Exnoii-  -

If  you  h  vo  such  o. thine  -s  a  snail  iron  drum  that  will 
hold  a  1J0  pounds  or  more’,  you  could  put  it  In  that,  i.nd  thoy 
could  send  t.n  automobile  after  it. •  if  not,  i  suppose  they  will 
have  to  send  several  non  with  stono  eider  jups.  fhoco  are  only 
random  suppostions,  but  you  will  see  ny  idea  is  to  pot  av.ay  from

My  dear  Mr.  Shaffner: 

Yours  of  January  10th  received  and 
glad  to  know  you  have  found  a  good  boat  but  imagine  you 
will  be  rather  cramped  for  room  comparing  the  Reposo  to 
the  Sachem. 

Hope  by  this  time  you  have  reached  Key  V/est 
and  settled  down  to  business.  Am  sorry  to  say  that  we 
are  still  frozen  in  solid  with  seven  to  eight  inches  of 
ice  and  has,  at  the  time  of  writing,  every  indication  of 
another  northeast  gale  .  Y/e've  had.  two  warm  days  but  the 
ice  did  not  melt  to  any  appreciable  amount.  All  the 
vessels  in  the  yard  have  been  very  short  of  coal  nut 
expect  six  cars  in  this  afternoon  so  'rfill  fill  up  to 
capacity,  plus  deck  load,  and  be  ready  for  the  first 
chance  to  break  through, as  you  know  we  are  to  pick  the 
screen  at  Cape  Lookout  and  then  go  to  Norfolk  for  powder 
and  projectiles  for  3"  guns.  Mr.  Edison  has  been  promised 
a  3"  gun  to  be  delivered  to  us  on  arrival  at  Key  West. 

I  think  we-  7/ill  all  be  satisfied  to  get  away  from  here 
as  time  is  beginning  to  hang  pretty  heavy.  During  the 
past  week  the  Government  sent  a  battle  ship  up  to 
Baltimore  to  break  a  passage  through  the  ice  for  s.  fleet  of 
steamers.  Have  forwarded  your  mail  and  a  package,  as  per 

Drop  me  a  line, now  and  then, as  to  how  you  are 
progressing  and  I  will  keep  you  posted  from  this  end  should 
anything  turn  up.  Best  regards  to  all  of  the  Edison  party,

Sub  j  eat'.  Special  Radio  Transmitting  Station. 

1.  Referring  to  your  recent  conversation  with  Captain  Sheppard, 
Radio  Division,  regarding  the  possibility  of  producing  sufficient  inter¬ 
ference  to  provent  submarines  in  the  English  Channel  from  communicating 
with  their  bases  in  Belgium  and  in  Germany,  without  at  the  same  time 
prohibiting  the  operation  of  Radio  stations  on  the  French  front  nor 
communication  between  friendly  ships.  This  problem  lias  been  given 
careful  consideration  and  it  is  believed  that  certain  methods  and  equip¬ 
ment  of  the  Signal  Corps  may  be  modified  end  adapted  in  such  a  manner 

as  to  provide  a  solution. 

2.  If  it  is  found  to  be  desirable  an  officer  can  be  detailed  to 
give  this  question  his  undivided  attention. 

3.  The  nature  of  the  problem  is  such  that  the  co-operation  of

|  NO  47. 

I  have  received  copies  of  your  Reports 
numbers  46,47,48,49,50  and  51,  which  have  boon  filed 
along  with  the  others. 

I  see  by  your  letters  to  Sir  Eric  Geddes, 
that  you  have  covered  these  in  communicating  with  him. 

But  you  have  suggested  one  more  plan  to  Sir 
Eric,  which  you  have  not  covered  by  a  report  to  Secretary 
Daniels.  It  is  the  idea  about  the  red  lights  carried 
by  Merchant  ships.  Do  you  not  think  it  would  be  well 
to  cover  this  in  a  separate  report  to  Secretary  Daniels?. 
If  so,  you  could  have  it  put  in  the  form  of  a  letter  to 
Secretary  Daniels,  and  call  it  IIo.  52. 

In  order  that  you  may  do  this,  I  will  attach 
hercto  a  copy  of  what  you  have  said  in  your  letter  to 
Sir  Eric  Geddes. 

/  Perhaps  you  are  not  aware  of  it,  but  our  practice 

in  sending  reports  to  Secretary  Daniels  was  to  send  a 
carbon  copy  to  his  personal  Secretary  and  also  carbon 
copy  to  Rear-Admiral  (formerly  Captain)  Smith.  If  this 
has  not  been  done  in  regard  to  Hos.  46  to  61,  inclusive, 
shall  I  send  the  copies  from  here? 


I  am  told  that  the  red  lights  carried  by  merchant 
ships  are  dangerous.  One  captain  reports  having  seen  28 
ships  at  night  in  a  convoy  of  34.  I  have  tried  a  light  at 
Annapolis  which  is  very  successful  whereby  all  the  ships 
can  have  lights  50  feet  above  water,  which  all  ships  can 
see  but  are 'invisible  from  submarines  on  account  of  the 
want  of  height  of  their  periscopes.  The  light  consists  of 
a  red  lamp  in  the  center  of  a  large  number  of  flat  discs 
covered  with  lamp  black.  These  parallel  the  ray  and  it 
can  only  be  seen  from  crow's  nest.  I  am  making  a  practical 
one  v/ith  small  gyroscope  to  obviate  effects  of  rolling  ana 
also  wind  guards.  If  you  desire  I  will  send  working  draw¬ 
ings  after  actual  trial  at  sea. 



Jamary  23,  1918. 

My  Soar  Mir.  Edison: - 

X  am  enclosing  you  a  memorandum  with 

reference  to  the  hydrogen  detector. 

Sincerely  yours. 

Mr.  Thomas  A.  Edison, 
o/o  Hotel  Powhatan, 
Washington ,  D.  C. 




2  31918 

MEMORANDUM  FOR  the  secredary  of  the  navy. 

Referring  to  conversation  with  you  relative  to  a 
hydrogen  detector,  designed  by  Hr.  Edison,  you are 
informed  that  I  have  had  this  matter  taken  up  with 
Mr.  Edison  in  person  with  the  following  results: 

It  was  decided  to  have  Mr.  Edison's  representative 
bring  one  of  the  instruments  to  Washington  to  he  in¬ 
spected  by  the  Bureau.  Mr.  Edison  sent  a  telegram  to  _ 
the  Orange  laboratories  and  this  instrument  was  brought 
down  by  Mr.  Warner.  The  instrument  was  inspected  by 
the  Bureau  on  the  morning  of  January  17  and  as  pre¬ 
viously  agreed  with  Mr.  Edison,  the  matter  was  taken 
up  with  the  Bureau  of  Standards  as  this  Bureau  had  done 
considerable  work  along  similar  lines.  A  letter  of  in¬ 
troduction  to  Dr.  Stratton  was  given  to  Mr.  Warner  and 
arrangements  made  on  the  telephone  to  have  the  instru¬ 
ment  examined  and  tested  if  desirable  while  Mr.  Warner 
was  here  in  Washington.  This  inspection  was  made  at 
the  Bureau  of  Standards  on  the  afternoon  of  January  ly. 

The  instrument  is  a  volumetric  gas  analysis  appar¬ 
atus.  operated  by  hand  and  requiring  direct  observation. 
It  indicates  change  of  volume  after  combustion.  The 
sample  bulb  is  so  large  in  proportion  to  the  size  of  the 
measuring  tube  that  the  instrument  is  extremely  sensi¬ 

The  following  is  quoted  from  the  Director  of  Bureau 
of  Standards'  report  relative  to  the  results  of  this 

"The  apparatus  is  made  of  glass,  and  is  fragile  and 
somewhat  bulky.  For  these  reasons,  as  7®1;}-  as 
it  is  not  automatic,  we  do  not  believe  it  is  especially 
suited  for  use  in  submarines.  Mr.  Wagner  conourB_ln  our 
opinion  that  an  automatic  instrument^f^^-typ^ow> 
boing-uae^ia  preferable."

The  boat  arrived  last  Monday  very  much  upset^  and 
worked  down  orew,  due  to  a  very  other  places,  whioh  were 

off  Brunswick,  Georgia,  and  on®  °r  £  Brunswick.  The  severe 

not  of  as  much  consequence  as  the  at or ,  off  Bruns* ^

The  Commandant,  Mr.  Trout,  told  us  that  If  we 
wanted  to  use  the  Lighthouse  tender  "Ivey",  (whioh  is  quite  a 
large  boat,  probably  300  feet)  he  would  be  glad  to  let'^us  have, 
and  he  would  also  let  us  have  any  of  the  small  boats  whenever  we 
need  them.  He  is  very  anxious  to  know  when  you  are  ooming  down 
and  wanted  to  know  if  I  sent  the  letter  he  wrote  to  you. 

All  of  the  material  which  you  ordered  has  arrived, 
also  a  gasoline  engine  and  a  one  and  a  half  kilowatt  generator.

Mr.  w.  H.  Me&dowcroft, 

Thos,  A.  Edison,  Laboratory, 
Orange,  H.  J. 

My  dear  Mr.  Ueadowerof t : 

I  have  been  waiting  to  reply  to  your  letters  of 
January  10th,  15th  and  l?th,  until  the  material  you  had  spoken  of 
shipping  me,  had  arrived.  This  material  has  been  coming  in 

for  the  last  eight  or  ten  days,  piece  at  a  time,  and  am  glad  to 
say  now  that  the  following  has  been  received: 

Two  volumns  of  Experimental  Science. 

Three  spools  copper  wire. 

Four  pieces  magnet  steel. 

One  book  on  Electrical  Magnets. 

Eight  boxes  of  material,  as  listed  in  vour  letter  Jan.  10. 

I  notice  in  your  letter  that  the  expressage  was 
prepaid  and  find  that  on  arrival  the  boxes  were  marked  collect,  and 
I  paid  $66.'50  expressage,  and  receipt  was  turned  in  with  my  weekly 
report,  dated  January  19th  to  Mr.  Kellow.  H  this  is  not  correct 
you  can  get  the  receipt  from  Mr.  Kellow  and  have  the  expressage 
refunded.  The  only  thing  now  lacking,  that  I  can  recall,  which 
I  asked  you  to  order,  is  as  follows: — 

One  book  on  Ampifyers  and  Audior.s. 
Five  gallons  storage  battery  solution. 
Six  hand  telephones. 

—  and  the  phonegraph  which  I  wired  you  to  send  on 
the  first  Mallory  boat.  This  Phonegraph,  I  needed  to  use  with  the 
accounting  records  for  Vesting  purpose,  and  at  the  same  time,  if  you 
had  some  of  the  "seconds"  cylinders,  to  be  used  on  the  same  phone¬ 
graph,  it  would  afford  quite  some  pleasure  to  our  men  at  odd  times. 

?■  I  am  enclosing  a  copy  of  the  packing  list  from 

Edison  Storage  Battery  Company,  and  the  dynamo  and  gasoline  engine 
which  arrive"’here  the  other  day,  and  I  know  nothing  about,  I 
have,  however,  written  Mr.  Edison  about  it. 

I  sent  by  Parcel  Post,  two  small  boxes  of  cigars; 
one  for  you  and  one  for  Mr.  Kellow.  These  cigars  were  especially 
recommended  by  the  Manager  of  this  big  cigar  factory,  the  "Gato" 
Company.  I  have  them  wrapped  so  that  they  will  not  loose  their 
moisture,  and  this  Manager  sai  if  they  cam  beljeptinthismolst 
condition  they  are  a  very  high  grade  cigar,  ana  the  one  wno 
smokes  them  should  enjoy  them. 

P95 e  ttwo: 

He  said  they  must  be  kep  in  thin  moist  condition 
at  all  times,  srs  if  they  once  get  dry  they  could  never  be 
brought  back  to  their  original  condition. 

The  weather  here  is  very  fine.  They  have  a  good 
Navy  Yard,  well  kept,  well  managed,  tney  nave  a  good  beat  anu 

t'get  some  place  now,  it  is  p'ttwrTjr  simply  cur  i 

The  Kali or y  boat  leaves  New  York  on  certain  days 
each  week,  which  date  they  do  not  give  out;  while  they  may  aa- 
„„rti^  a  certain  date,  they  lever  leave  on  them,  but  i.  you 
would'  identify  yourself  with  one  of  their  Officers  they  would 
toll  vou  confidentially,  the  date  they  are  to  sail,  anu  11

nothing' about  the  expense,  than  by  shipping  “  f  th

My  dear  Mr.  Shaffner: 

I  have  received  your  favor  of  the  25th  inst., 
and  am  very  glad,  indeed,  to  get  your  report  as  to  the  receipt  of 
some  of  the  items  which  have  been  forwarded  to  you. 

According  to  your  letter,  the  items  lacking  are  as  follows: 

1  Book  on  Amplifyers  and  Audions; 

5  gallons  Storage  Battery  Solution; 

6  hand  telephones; 

Phonograph  and  records. 

I  will  report  on  these  as  follows:  She  Book  has  been  out 

of  urint.  ffhere  will  be  a  new  edition  out  on  Friday  of  this  week, 
and  vour  copy  will  be  forwarded  then.  As  to  the  battery  solution 
it  was  forwarded  to  you  by  Express  on  the  21st  instant  Bn* e®ephones 
there  now.  I  have  sent  a  tracer.  As  to  the  six  hand  telephones, 
four  of  them  (the  200  Ohm  type)  had  to  be  made  up  specially.  The 
Wfisiern  Electric  people  have  been  very,  very  busy,  and  I  have  been 
rushine  them  on  it?  They  now  promise  to  have  them  ready  tomorrow 

St Ki  “  e'&sAs.: 

was  sent  by  Mallory  boat  last  Friday,  and  you  may  have  it  before  this 
letter  reaches  you. 

In  regard  to  the  eight  boxes  of  material,  I  am  tfild  they  were 
marked  "prepaid"  when  sent  from  here.  However,  weh&ve  not  received 
a  bill  from  the  Express  Company,  and  if  we  do,  we  shall  not  pay  i  , 
but  will  show  the  receipt  for  the  expressage  paid  by  you. 

-  I  note  your  remarks  in  regard  to  shipping  by  the  Mallory  boat, 
and  shall  be  guided  accordingly.  Probably  the  best  thing  for  me  to 
do  would  be  to  go  over  to  the  pier  and  make  friends  with  some  one 
"  who  will  see  that  our  stuff  is  forwarded  promptly.  I  don  t 

when  I  shall  be  able  to  get  over  in  time  to  send  out  0 

■  in  that  way,  so  I  will  send  them  tomorrow  morning  by 
Special  Delivery  and  wish  you  would  tell  me  how  long  it  takes  ^hem 
to  reach  vou.  I  feel  a  little  dubious  about  sending  small  packages 
by  the  Mallory  boat  for  fear  they  may  get  lost  amongst  so  much  big

had  been  promptly  acted  upon  an  effeotive  and  useful  laboratory, 
larger  than  any  other  whioh  oould  have  been  oonstruoted  with  the 
same  money,  would  now  be  in  exletenoe,  of  ample  resources  and 
oapaoity  to  have  enlisted  the  professional  activities  of  hundreds 
of  skilled  oivilian  scientists  and  workmen. 

Tfho  oan  reokon  the  possible  value  of  suoh  work  during 
the  past  few  months  and  at  the  present  time,  or  measure  the 
possible  loss  in  life  and  property  because  of  its  laok,  despite 
the  many  activities  of  the  members  of  the  Board  in  other  laboratories 
and  workshops?  With  the  facilities  whioh  would  have  been 
available  it  is  beyond  question  that  some  at  least  of  the  39,000 
proposals  whioh  have  been  submitted  to  the  Consulting  Board, 
fantastio  as  the  majority  of  them  are,  might  have  been  given  a 
deserved  opportunity  of  development  instead  of  being  consigned 
to  an  early  grave  with  thanks  because  of  the  impossibility  of 
providing  for  suoh. 

The  oiroumBtanoes  resulting  from  this  inaotion  have 
seriously  reaoted  on  this  Board.  It  has  lost  caste,  its 
recommendations  are  largely  unheeded,  its  activities  are  ourtailed, 
its  authority  largely  imaginative. 

Whatever  usefulness  is  apparent  is  largely  that 
represented  by  the  efforts  of  individuals,  often  working  on 
their  own  responsibility  and  expenses,  but  sometimes  aided  by 
the  moderate  appropriations  authorized  out  of  the  laboratory 
fund.  With  regard  to  this  last,  neither  you  nor  I  personally 
have  probably  any  oause  for  oomplaint. 

I  do  not  know,  of  course,  in  detail  what  your  own 
activities  have  been,  nor  to  what  extent  you  have  thuB  far  found 
any  partioular  looality  or  facilities  necessary,  but  my  own 
experience  has  emphasized  oertaln  vital  faots  as  to  the  needs  of 
this  laboratory,  and  these  have  not  been  lessened  by  the 
assumption  for  myself  and  assistants  of  personal  risks  not  usually 
sought  after,  and  emphasized  by  the  reoent  aooident  at  the 
Newport  Torpedo  Station. 

Believing  that  after  all  that  oan  be  done  for  the 
prevention  of  issue,  protection  against,  and  detection  of 
submarines,  whioh  have  constituted,  and  unhappily  still  constitute 
to  an  extent  generally  under-rated,  the  gravest  menace  of  the 
war.  I  believe  that  for  their  destruction  it  is  neoessary  to 
be  "able  to  attaok  them  both  above  and  below  water  anywhere  within 
range  of  gun  fire.  To  this  end  I  have  been  aotively  engaged  in 
the  development  of  various  kinds  of  ordnance  apparatus,  including 
depth-oharge  meohanisms  and  sub-aqueous  and  delay-aotion  fuses, 
following  that  development  from  oonstruotion  to  tests. 

This  work  has  taken,  or  in  the  near  future  will  take 
me  to  the  Ordnanoe  Bureau  in  Washington,  the  proving  ground  at 
Indian  Head,  the  shell  works  at  Gillespie,  N.  J.,  the  Dupont  works 
at  Pompton,  the  naval  depot  at  Iona  Island,  the  navy  yard  in 
New  Pork,  the  waters  off  the  ooast,  and  the  torpedo  station  at 

These  developments  require  of  neoessity  drafting  and 
maohine  work,  the  preparation  and  handling  of  wet  and  dry  fulminates, 
the  loading  of  detonators,  boosters,  shells,  fixed  ammunition 
and  bombs  with  high  explosives,  and  land  and  water  tests  of  the 
finished  produo ts. 

Save  for  the  meohanioal  work  not  a  single  one  of  these 
vitally  neoessary  things  would  be  permitted  to  be  done  in  the  oity 
of  New  York  or  any  Navy  Yard  in  the  oountry,  but  everyone  of  them 
oould  be  carried  on  continuously  and  with  safety  in  any  properly 
equipped  and  suitably  located  experimental  station  and  research 
laboratory  having  the  oharaoteristios  set  forth  in  our  report, 
while,  on  the  other  hand,  the  machine  work  alone  oould  be  done 
in  a  hundred  shops. 

Already  the  oountry,  impatient  with  the  preparations 
made  for  war  and  increasingly  appreciative  of  the  great  task 
ahead  of  us,  is  beooming  oritioal  and  justly  so.  It  demands 
oonstruotive  aotion  and  will  not  brook  refusal  to  use  the  means 
it  places  in  the  hands  of  its  servants  at  a  time  of  this  national 
orisis.  It  is  up  to  the  Board  to  make  good  and  to  relieve 
Secretary  Daniels  from  a  possible  grave  embarrassment  as  an 
anti-olimax  to  the  splendid  work  whioh  has  already  been  done  in 
naval  preparation. 

Every  member  of  the  Board  is  impatient  at  our  impotenoy 
and  ohafes  at  conditions  whioh  are  fast  becoming  intolerable. 

For  the  reasons  set  forth  in  our  Committee  report  I 
have  strongly  favored  Annapolis,  but  in  the  hope  of  some  compromise, 
and  if  unhappily  not  that  then  the  humiliating  relinquishment 
of  our  responsibility,  I  am  willing  to  join  the  rest  of  the  Board 
in  either  of  two  oourses : 

First:  An  immediate  recommendation  for  the  ereotidn 
of  the  laboratory  on  plans  to  meet  the  approval,  of  the  Department 
.on  the  Bellevue  Magazine  Site  in  Washington,  whioh  in  view  of  the 
ohanged  conditions  wrought  by  the  war  I  believe  the  rest  of  the 
Board  would  unanimously  agree  to ,  or 

Second;  Bequest  Secretary  of  the  Navy  that  the 
officers  and  members  of  the  Board  be  relieved  from  father 
responsibility  and  the  selection  be  left  to  the  Bureau  Chiefs, 
to  whom  all  papers  should  be  submitted. 

Frankly,  we  have  no  right  to  let  this  matter  drag 
along  further.  We  have  been  made  trustees  for  the  ereotion  of  a 
vital  naval  establishment,  and  we  should  either  fulfill  our 
obligations  or  yield  our  privilege,  and  if  we  do  not  take 
oonstruotive  aotion,  and  the  Secretary  remains  unwilling  to,  then 
it  may  be  accepted  as  a  certainty  that  Congress  will  inquire  the 
whys  and  wherefores  of  the  delay  and  take  unto  itself  the  direction 
of  final  deoision. 

Page  4  - 

The  Board,  meets  again  this  week  in  Hew  York; when 
it  will  again  take  up  this  question.  I  hope  that  you  will  see 
your  way.  either  direotly  or  thru  some  representative,  to 
express  at  that  time  your  oooperation  in  one  or  other  or  the 
proposals  I  have  made,  and  in  this  way,  irrespective if 
of  the  personal  wishes  of  any  of  us,  remove  the  stumhling  hlook  in 
the  way  of  the  Seoretary  of  the  Navy  proceeding  without  further 
delay  in  this  vitally  necessary  matter.

I  enclose  herewith  three  letters  which  have  come  for 
you.  through  the  mails.  X  also  enclose  a  letter  from  admiral 
Yfei.-  Strother  Smith  relative  to  a  local  civil  engineer  who  wanted, 
to  see  you.  I  called  up  the  man  with  a  view  to  seeing  him  and 
get  a  memorandum  of  what  he  wanted  to  say,  to  send  to  you.  ..nat 
he  had  to  propose  was  of  such  importance,  however  that  u  was 
for  ■'■'•our  ears  exclusively,  i  gathered,  as  admiral  uinith  evidenu- 
ally’did,  that  the  country  will  manage  to  get  along  wimon,  his 
idea  for  a  while  at  least. 

mpere  have  been  some  interesting  hearings  here  recently 
bearing  unon  some  of  the  problems  you  have  under  investigation 
including"]. ajor  a.  A.  Killifcen,  Dr.  Vfnitney  and  Hr.  C  i,.  ^veleth, 
whom  T  believe  you  talked  with,  and  several  o  on  er  s .  if  „ ou  so 
desire,  I  can  have  conies  made  to  send  you  or  at  least _ extracts 
of  their  hearings  which  I  think  would  be  particularly  interesting 
to  you. 

On  account  of  the  increased  work  in  our  office  and  the 
possibility  of  a  man  being  useful  in  making  such  copies  and 
other  work  for  you,  I  have  been  allowed  an  additional  stenogra¬ 
pher  so  that  you  will  not  be  depriving  anyone  else  ox  the  ser¬ 
vices  of  a  man  any  time  that  you  may  have  any  work  that  he  can 
do  here  while  you  are  in  Florida  or  after  you  return, 
do  not  hesitate  to  have  me  look  up  any  references  or  co_lect 
any  data  you  may  desire. 

Two  days  after  you  left  here  we  had  a  much  bigger  snow 
storm  than  that  on  the  day  of  your  departure  and  you  were  indeed 
fortunate  to  escape  it.  V/ith  the  two  storms  there  was  -flat 
eleven  inches  of  snow  and  practically  the  only  street  tiaffic 
was  on  the  car  tracks.

To  the  Members  of  the  Naval  Consulting  Board, 

Dear  Sirs: 

Please  be  advised  that  the  next  meeting 
of  the  Naval  Consulting  Board  v/ill  be  held  on 
FEB  16  1918  in  the  Carnegie  Institution, 
Washington,  D.  C. 

The  preliminary  meeting  begins  at  nine 
o'clock  and  the  formal  meeting  at  ten. 

Very  truly  yours, 




Several  naval  officers  with  whom 

I  have'  talked  and  who  have  had  experience  in  the  danger 
zone,  and  one  merchant  steamer  captain  who  traveled  in 
convoy  with  the  "Valeria" ,  have  all  said  that  they  be¬ 
lieved  in  the  system  of  concealment  which  was  followed 

out  in  the  case  of  the  "Valeria",  hut  as  yet  we  have 
no  offioial  report  on  the  "Valeria"  from  the  United 
States  Navy  so  far  as  I  have  been  able  to  learn. 
Faithfully  yours,

Mr.  Thomas  A.  Edison, 
Edison  laboratory. 
Orange,  H.  J. 

Dear  Sir: 

V/e  ere  sending  you  herewith  a  copy  of  a  Digest  which 
contains  information  largely  culled  from  the  repor ts  ' which  have 
been  made  by  the  various  outstanding  Committees  at  the  Board  on 
inventions  which  have  been  submitted  to  them  by  the  Committee  of 
Examiners.  As  many  of  these  reports  were  made  months  ago,  some 
of  the  opinions  expressed  should  undoubtedly  be  revised  so  that 
the  information  will  be  up  to  date,  and  the  Examiners  would 
greatly  appreciate  it  if  you  would  kindly  read  over  this  Digest 
and  make  any  corrections,  eliminations  and  additions  which  occur 
to  you.  The  heading  preceding  each  paragraph  contains  the 
subject  of  the  invention,  the  author  of  the  opinion  and  the  name 
of  the  inventor. 

Since  the  organization  of  the  Committee  of  Examiners, 
nearly  42,000  letters  have  been  received  from  inventors  and 
nearly  as  many  inventions  have  been  passed  upon,  and  only.  1362 
of  these  have  been  referred  to  a  Board  Committee,  or  about  4%. 

So  far  this  year  only  one-half  of  one  per  cent  of  the  inventions 
submitted  have  been  referred  to  Committees  of  the  Board, 
indicating  that  the  Examiners  have  nade  good  use  of  the  infor¬ 
mation  they  have  gleaned  from  the  reports  of  Committees,  and 
have  been  able  in  a  large  number  of  cases  to  act  without 
assistance.  It  is,  therefore,  evident  that  the  Examiners 
should  have  up-to-date  information. 

Thanking  you  in  advance  for  your  kind  attention  in 
this  matter,  and  hoping  that  we  may  hear  from  you  in  the  near" 
future,  we  remain. 




CLASS  1. 


This  method  bas  been  used,  a  great  deal  In  the  Worth 
Sea  by  England  and  Franoe.  The  nets  there  have  been  about 
3,000  feet  in  length,  but  are  found  to  bunch  and  lean  over  to 
almost  a  prohibitive  degree,  if  towed  at  any  praotloable  speed. 
The  behaviour  of  nets,  either  towed  or  anchored  in  a  current 
is  very  difficult  to  oompfehend  until  seen. 



The  false  bow  mine  protector  is  all  right  for  the  bow, 
but  the  mines  as  soon  as  they  roll  off  the  end  of  it,  would  oome 
back  and  hit  the  ship,  and  400  pounds  explosion  of  T.N.T.  at 
any  distanoe  outboard  at  which  it  would  he  practical  to  carry 
suoh  a  devioe  would  not  only  blow  away  this  proteotor  hut  would 
injure  the  ship.  This  amount  of  explosive  would  he  very  in¬ 
jurious  to  ordinary  ship s 1  hulls  at  any  suoh  distanoe. 




All  torpedoes  have  net  cutters. 


W.L.R.  1 

There  ie  no  objeotlon  to  the  combination  of  mines  or- 
bombs  with  a  net,  provided  they  are  made  safe  to  handle.  The 
Navy  has  several  types  of  mines  or  bombs  wfeioh  are  believed  to 
be  entirely  satisfactory  for  this  purpose. 









A  very  imperceptible  tidal  ourrent  onuses  the  net 
to  lhp  way  over  to  one  side  and  to  sink  the  type  of  the  net  to 
a  surprising  extent. 


Nets  are  of  little  use  unless  upper  rail  oomes  very 
close  to  the  surface,  as  submarines  run  on  the  surface  95/3  of 
the  time. 




There  seems  to  be  a  hesitancy  on  the  part  of  all  the 
Navies  to  employ  nets  with  bombs  forming  a  part  of  them,  owing 
to  the  great  danger  in  the  very  rough  handling  which  these  nets 
invariably  reoaive,  especially  when  attempts  are  made  to  lay 
them  in  rough  weather. 


This  method  has  been  used  a  great  deal  in  the  North 
Sea  by  England  and  Franoe.  The  nets  there  have  been  about 
3,000  feet  in  length,  but  are  found  to  bunon  and  lean  over  to 
almost  a  prohibitive  degree,  if  towed  at  any  practicable  speed. 
The  behavior  of  nets,  either  towed  or  anohored  in  a  ourrent  is 
very  difficult  to  oomprehend  until  seen. 



All  torpedoes  have  net  cutters.

Unreliability  is  introduoed  by  eleotrioal  oontaots. 


The  magnetic  feature  has  been  and  is  now  under  very 

careful  investigation  by  a  oommittee  of  this  Board  and  to  date 
has  been  found  extremely  unsatisfactory,  owing  to  the  extremely 
short  distance  through  which  magnetism  is  found  to  be  at  all 


This  arrangement  has  been  tried  in  England  with  a 
decoy  and  has  not  bean  sufficiently  productive  of  result's  to 
warrant  its  continuance. 


This  would  be  a  good  device  if  the  whereabouts  of  the 
submarine  were  known.  Thera  are  a  great  many  perfectly  success¬ 
ful  methods,  including  the  now  quite  well  known  depth  charge  of 
the  U.  S.  Navy,  for  dealing  with  the  submarine  when  its  where¬ 
abouts  is  determined.  The  problem  lies  rather  in  the  looating  of 
the  submarine. 




Magnets  would  not  hold  to  a  boat  running  through  the 
water  and  therefore  the  scheme  is  lmpraotiflable.  The  main 
point  would  be  to  locate  the  submarine.  Magnets  are  found  al¬ 
most  valueless  for  the  purposes  named.  When  the  submarine  is 
once  located  very  simple  means  are  at  hand  for  disposing  of  itl 


The  difficulty  with  this  devioe  is  that  the  submarine 
usually  stands  off  at  a  distance  laterally  from  the  boat.  A 
submarine  always  sees  the  boat  before  the  boat  Bees  the  submarine. 
The  present  depth  mines  do  not  require  special  devioes  for  handl¬ 
ing  and  are  probably  better. 


A  oontaottdepth  mine,  rising  to  the  surfaoe  if  failing 
to  oontaot,  is  unnecessary  and  Inadvisable.  The  essenoe  of  the 
depth  oharge  is  that  it  explodes  in  the  vicinity  of  the  submarine 
in  case  it  fails  to  strike  the  boat  Itself.  The  use  of  the  oon¬ 
taot  depth  mine  presupposes  the  neoessary  aoouraoy  to  strike.  The 
reoovery  feature  is  of  no  partloular  value  and  would  neoessitate 
numerous  safety  precautions  to  insure  absolute  safety  in  picking

All  the  evidenoe  that  we  oan  oolleot  from  ' those1 with 
experience  in  the  operation  of  torpedoes,  shows  that  it  is  hope¬ 
less  to  attempt  to  protect  against  them  after  they  are  onoe  fired. 
The 8 interval  between  firing  and  hitting  is  usually  so  short  that 
it  is  diffioult  to  aot  within  this  period. 



It  is  not  understood  that  there  is  any  great  demand 
for  a  means  for  firing  a  large  number  of  t orpedoes  ( a^ly,  as

#8  tioable.  Torpedoes  running  at  or  near  the  surfaoe  are  not 

considered  practicable,  nor  are  torpedoes  directly  operated  by 
oombustion  engines  as  motive  power. 


No  magnet,  unless  in  actual  oontaot  with  the  steel  ship, 
would  give  magnetism  enough  to  control  the  torpedo.  The  ricio- 
#9  ulouBly  small  distances  through  which  these  magnetio  devices 

are  found  to  be  effective  render  them  undesirable  and  impractic¬ 
able.  Any  automobile  torpedo  is  very  expensive  and  requires 
expert  attention  and  is  therefore  undesirable. 


A  great  many  nest  arrangements  of  torpedoes  have  been 
considered,  also  torpedoes  combined  with  nets.  The  Government 
#19  does  not  believe  that  any  of  these  combinations  are  as  praotl- 
oable  as  means  that  are  now  at  hand. 



The  sound  made  by  submarines  when  traveling  under  water, 

#11  at  a  distance  of  a  mile  or  more,  is  so  faint  and  Indefinite  that 

it  is  not  believed  that  any  controlling  devioe  depending  on  sound-waves 
for  aotlon  oould  be  made  operative. 


Torpedoes  are  not  easily  deflected  in  this  manner.' 

Heavy  charges  have  been  exploded  experimentally  dlreotly  in  front 
#13  of  and  at  the  aide  of  torpedoes,  for  the  purpose  of  determining 
the  possibilities  of  defleotlng  them  from  their  course.  The 
regulating  gyrosoope  of  a  torpedo  immediately  brings  it  back  to 
its  normal  course,  so  that  such  method  may  be  considered  as  in¬ 
effective.  Moreover,  it  should  be  understood  that  usually  there 
is  no  knowledge  that  a  torpedo  is  oomlAg  until  it  actually  bits 
the  vessel. 



An  extended  series  of  experiments  have  been  made  in 
this  direction  during  the  past  few  years,  by  engineers  in  this 
#13  country,  and  some  interesting  results  have  been  obtained  under 

favorable  conditions.  Unfcrtunately ,  however,  in  actual  warfare 

favorable  conditions  are  seldom  seoured.  In  all  varities  of 
selective  wireless  control,  the  principle  difficulty  is  to  obtain 
the  absolute  certainty  of  oontrol  which  such  system  must  possess 
to  be  servioable.  Any  wireless  oontrol  arrangement  depending  on

oneinv  ona  friendly  ships  or  wireless  stations,  ana  suen  xntex- 
ference^isllkely  to  he  attended  with  unexpected  results. 

For  this  reason  no  practical  use  has  been  made,  up  to  tne  pres¬ 
ent  time,  of  suggestions  of  this  nature.

It  is  the  opinion  of  Naval  Authorities  that  no  one-man 
'  or  two-man  submarine  can  he  built  which  will  prove  effective  in 
anv  degree.  The  fundamental  difficulties  of  opera  cion  of  such 
boats  render  them  impracticable  instruments ,  deserving  ox  no  ex¬ 
penditure  by  the  Government. 




One-man  "Baby"  submarines  would,  on  account  of  their 
low  speed,  limited  range  of  action  and  unseaworthineso ,  be  of 
very  little  use  today. 



.  As  it  is  impossible  to  see  the  invisible,  submarine 
cannot  fight  submarine.  Infested  as  have  been  the  waters  of  the 
North  Sea  and  English  Channel  no  case  is  Known  where  one  submar¬ 
ine  has  succeeded  in  sinking  another.  An  Austrian  submarine 
did  sink  an  Italian,  but  the  latter  was  surface  cruising.

CLASS ' 6 

Tlie  sound  made  by  submarines  when  traveling  under  water , 
at  a  distance  of  a  mile  or  more ,  is  so  faint  and  indefinite  that 
it  is  not  believed. that  any  controlling  device  depending  on  sound 
waves  for  action  could  be  made  operative. 



Tests  made  on  an  actual  submarine  have  shown  that  the 
magnetic  effects,  due  to  this  mass  of  iron,  are  auite  limited  in 
vanpe.  Por  instance,  at  150  feet  distance  tne  im  giietic  eifect, 
duetto  a  submarine,  is  only  about  as  much  as  *lio  ear tn_  s  mag¬

from  other  influences. 


Experiments  are  being  tried  on  underwater  illumination, 
but  it  will  be  some  time  before  it  is  known  to  what  extent  boats 
may  be  seen  by  searchlight  beams  or  light  from  other  sources. 




Underwater  illumination  depends  upon  the  amount  of 
foreign  material  in  the  water.  Around  England  the  water  is  so 
■>U  murky  that  a  range  of  any  light  under  water  is  extremelyJLimited. 
On  the  other  hand,  along  some  parts  of  the  American  ooa^,  uno 
range  is  several  times  as  great,  due  to  the  purity  oi  me  vaier. 


One  of  the  difficulties  with  the  simple  form  of  sound 
detecting  device  is  that  the  undesirable  sounds  and  disturbances 
do  not  come  from  a  definite  single  source,  which  would  permit  of 
their  blotting  each  other  out,  but  they  cornc  from  many  direc cions, 
especially  in  rough  weather.  The  principle  is,  however,  receiv¬ 
ing  careful  study,  and  the  same  mry  be  said  of  tho  troaibone  slide, 
which  was  introduced  into  the  problem  a  long  time  ago. 




That  the  permeability  of  water  is  many  times  greater 
than  that  of  air  is  not  borne  out  in  practice,  and,  in  fact,  we 
can  find  no  difference  in  the  magnetic  indications  m  water  and 
in  the  air.  The  magnetic  effect  due  to  a  submarine  at  a  distance 
of  100  yards  is  so  minute  that  impossibly  delicate  apparatus  is 
noeded  to  show  such  effect.  Experience  shows  that  the  dolioacy 
is  very  much  greater  than  is  permissible  on  shipboard. 





Am  extended  series  ox  experiments  have  been  uvi.dc  in

It  is  £;  very  old  expedient  to  attempt  to  relieve 
tl:e  clock  on  projectiles  slid  they  have  "boon  many  times  tried 
and  found  failures.  It  is  necessary  to  vet  high  pressure  on 
the  base  of  a  projectile  in  order  to  impart_to  it  the  required 
velocity.  *  hotter  rocult  would  he  hy  leaving  out  the

She  navy  Department  is  already  employing  a  satis¬ 
factory  non-ricocheting  projectile  which,  in  the  opinion^of 
the  committee,  is  superior  to  the  device  presented,  anc.  for 
that  reason  the  committee  does  not  recommend  that  experiments 
he  conducted  with  the  latter  at  the  expense  of  the  Government.

The  I!avy  has  one  or  more  types  of  shell  that  pene¬

along  .the  line  of  straighten  under  water  trajectory  and  reduced 
und or  water  resistance.  The  screw  nosed  type  has  not  boon  tried, 
hut  it  would  seem  that  inventors  are  laboring  under  a  misappre¬ 
hension;  vis.,  that  the  shell  will  screw  its  way  into  the  v/atcr- 
whoreas  a  shell  rotates  only  once  in  about  25  to  SO  calibros- 
and  the  fraction  of  a  revolution  which  it  makes  while  entering 
the  water  is  negligible. 



Tlid  principle  objections  to  chain  shot  are  its  limited 
range  and  its  lack  of  accuracy. , as  compared  to  rifle  projectiles. 
To  got  a  high  velocity  or  a  moderate  rango  requires  a  very  strong 
construction,  and  may  not  he  feasiblt.  Used  against  airships  and 
aeroplones  which  operate  ct  from  10,000  to  15,000  feet  altitude, 
chain  shot  will  he  entirely  inadequate  both  in  range  and  accuracy 
of  fire. 








Experiments  have  shown  that  chain  shot,  due  to  the  in¬ 
creased  air  resistance,  does  not  travel  accurately  for  any  con¬ 
siderable  distance.  Proposals  to  have  chain  replace  1h  e  bul¬ 
lets  in  shrapnel  shell  have  been  made  aid  proposals  to  have  a 
chain  attached  to  balls  fired  from  separate  cannon  have  also 
been  suggested.  The  air  resistance  of  the  chain,  no  matter  in 
what  manner  it  is  projected,  is  irregular  and  very  high,  so  that 
its  trajectory  is  erratic  and.  its  range  short.

The  device  ia  without  useful  novelty  or  practical  merit 
for  the  reason  that  Centrifugal  Gtas  would  he  entirely  valueless 
in  modera  warfare  in  competition  with  other  means  now  in  use. 



Tba  Centrifugal  Gun  of  any  type  is  useless  in  modern 
warfare  in  competition  with  other  means  now  in  use.  No  model 
is  needed  to  pronounce  upon  this  device. 



It  is  the  sense  of  the  Committee,  that  the  advantages, 
if  any.  of  this  device  are  not  sufficient  to  warrant  the  ad¬

The  advent  of  the  automatic  gun  in  1887  put  all  other 
forms  of  machine  guns  out  of  the  running.  There  are  so  many^ 
advantages  possessed  by  the  automatic  gun  that  it  is  nov  worm 
while  to  eive  a  thought  to  any  other.  Many  suggestions  have 
been  madegto  build  automatic  guns  with  a  plurality  of  tarrels^, 
hut  it  has  been  found  to  be  far  more  practical  to  use  the.  sin¬

to  duplicate  the  entire  gun. 




The  substitution  of  explosive  gas  mixtures  for  high

The  Wight  seaplane  in  England  has  folding  features  which

An  airplane  having  a  great  many  planes,  absolutely  flat  and  100 
feot  and  50  feet  wide,  placed  one  foot  apart.  It  is  claimed  that 
the  planes  Being  flat  no  undulations  of  air  Between  the  planes  will 
take  place,  thus  making  it  possible  to  U3e  u  groat  many  planes,  very 
wide  from  front  to  Back  and  placed  close  together.  The  resistance 
would  Be  so  great  that  the  number  of  engines  required  to  operate  it 
'successfully''would  tax  practically  all  of  its  sustaining  power. 

Also,  undulations  would  no  doubt  take  place  Between  such  wide  planes. 


When  an  effort  is  made  to  lay  a  torpedo  By  un  aeroplane,  not 
only  does  the  horn  suffer,  But  the  torpedo  itself  is  likely  to  Be

pedo  under  conditions  that  in  no  way  resemble  airplanes  speeds  ri¬ 
cochets  and  tumbles  in  the  most  disastrous  manner.  The  method  sug¬ 
gested  for  protecting  the  horns  might  Be  good  But  it  i3  so  necessary 
to  work  quickly  that  the  soluble  matter  would  have  to  Be  wholly  dis¬ 
solved  in  a  very  short  interval  of  time,  so  as  to  allow  of  operation 
when  the  target  is  finally  reached.

A  disadvantage  of  this  construction  is  that  wooden  bulk¬

Inverted  truncated  cones  might  1)e  servicuble  hut  it  might 
ho  bettor  and  simpler  to  use  pyramids  instead  of  cones.  As  long 
as  those  were  placed  at  such  an  angle  that  the  roll  of  the  boat 
would  not  cause  them  to  reflect  the  sky, the  result  ought  to 'oe 
very  good.  A  cylindrical  mirror  would  show  a  bright  line  on  one 
6  3ide  like  a  polished  shaft  and  any  flat  vertical  surface  might 
reflect  the  s!:y  when  the  boat  rolled.  The  enclosed,  sketch  shows 
an  arrangement  which  would  probably  be  quite  effective  in  hiding 
a  oeriscope  if  tho  mirror  was  turned  toward  the  vessel  attached. 
Tho  arrangement  shown  in  fig.  2  corresponds  to  your  uono  idea. 

The  objection  to  that  is  that  on  each  pyramid  or  cone  surface, 
v/e  would  see  the  reflection  of  the  one  below.  Such  an  arrange¬ 
ment  could  easily  bo  experimented  with  and  might  be  worth  while.

Bom'os  with  oaraehutea  have  Been  tried,  hut  they  carry 
so  much  sail  that  they  are  totally  unreliable  on  account  of  the 
enoromous  factor  of  drift,  which  always  is  an  extremely  uncertain 
factor.  Owing  to  theso  circumstances  this  device  cannot  ho  rec¬ 
ommended  .

Tlioro  is  no  question  that  the  visible  matter  in  smoko 
can  he  scrubbed  out  with  certain  types  of  apparatus.  The 
whole  subiect  has  boon  considered  at  length,  and-  the  conclu¬ 
sion  reached  is  that  to  handle  the  quantity  of  gases  erai Mod 
from  a  vessel's  stack  will  require  in  most  cases  such  an 
amount  of  machinery  and  apparatus,  us  well  as_ power ,  as  to 
make  the  use  of  such  a  system  inadvisable.  Tne  small  sub¬ 
marine  chasers  are  equipped  with  internal  coiubustiou  engines 
and  emit  no  smoko.  Torpedo  Boats  and  res  troy  ore  use  on 
Puel ,  and  can  suppress  or  emit  smoke  at  will. 


This  whole  matter  of  eliminating  visible  smoke  by 
scrubbing  the  stack  gases  has  boon  very  fully  coneiaorod 
in  connection  with  the  work  of  the  Chip  Protection  Commit toe 
of  the  Emergency  Fleet  Corporation,  and  it  utc  been  ueciuou 
that  it  cannot  bo  applied  without  rich  f enouc  j.r. 
as  to  render  its  use  inadvisable. 


When  the  Mackey  designs  were  first  used  the  design  was 
put  on  in  lines  and  angles,  using  the  colors  in  broad  masses 
without  spots..  The  Navy  is  using  more  of  the  red,  green  ana 
violet,  than  they  did  at  first.  Combined  with  the  red,  green 
and  violet,  the  Bavy  uses  black  and  white.  By  using  violet 
deep  instead  of  black  ana  by  using  light  green,  red  or  light 
violet  instead  of  pure  white,  there  is  a  reaction  with  the 
ray- filter  and  this  reaction  gives  greater  confusion  to  the 
design.  Two  models  of  submarines  have  been  painted  to  rep¬ 
resent  'fish,  one  for  northern  waters  ana  one  for  southern 
waters,  ana  an  interesting  design  of  boat,  some  Dazzle  and  . 
some  parts  painted  to  vibrate  and  go  out,  le&vmg_  the  Dazzle 
only.  Two  police  boats  were  pointed,  one  for  daylight  op¬ 
erations,  the  othor  for  evening  and  night  work.  Professor 
John  Treadwell  Hichols  of  the  American  Museum  oi  natural 
History  has  assisted  and  directed  the  painting  of  two  (2) 
scale  models  of  submarines,  explaining  how  a  fish  that  swims 
near  the  surface  is  protected  from  detection  by_ color,  light 
and  shade.  The  ray-filter  is  also  being  studioa,  so  that 
color  in  combination  with  the  Dazzle  design  will  prevent  a 
clear  outline  being  obtained.  The  drawings  made  by  the  of¬ 
ficers  of  the  I.K.M.  show  that  red,  green  and  violet-blue, 
oombined  with  black,  are  at  present  the  colors  most  used. 


An  innovation  in  some  of  the  vessels  building  at  Portland, 
Ore.,  for  the  Government  is  that  they  will  bo  mastless  end  m 
nlaoe  will  have  collapsible  steel  towers  that  can  be  raised 
when  in  portlnd  utilized  in  the  handling  of  cargo.  This  design 
was  adopted  to  reduce  visibility  when  at  sea  in  the  war  zone.

Mr.  Thomas  A.  Edison, 
Report  on  Order  #6013: - 

Y/e  have  been  testing  out  a  one-step  amplifier  connected 
to  one  of  the  receiving  stations  and  have  been  able  to  obtain 
records  from  a  distance  of  over  five  miles  that  were  easily 

Our  tests ^to  date  have  been  made  to  determine  the  proper 
winding  of  the  input  coils  to  use  with  the  low  frequency  sound 
of  the  gun  and  which  would  give  the  best  results  with  our 
recording  apparatus.  We  expect  to  have  uniform  amplifier  equip¬ 
ment  for  all  three  points  of  our  base-line  installed  this  week 
when  we  can  make  observations  to  determine  the  degree  of  accuracy 
in  estimating  a  source  of  sound  approximately  five  miles  distance. 

We  seem  to  have  ample  power  in  our  receiving  apparatus  as  the 
record  at  five  miles  is  very  good  and  easily  read,  yet  the  sound  of 
the  gun  is  just  barely  audible  to  the  unaided  ear.

Mr.  S.  C.  Shaffner, 

U.  S.  Haval  Station, 

Key  West,  Ela. 

My  dear  Mr.  Shaffner: 

Allow  me  to  thank  you  for  your  note  of 
the  8th  instant.  It  was  very  welcome,  and  I  am  indeed 
glad  to  learn  that  some  special  preparations  had  been 
made  for  observing  Mr.  Edison's  birthday.  From  your  de¬ 
scription  it  looks  as  thoueh  everything  would  be  made 
very  pleasant  for  him,  and  I  hope  that  the  occasion  will 
be  enjoyed .by  everyone. 

A  number  of  Mr.  Edison's  old  associates,  com¬ 
posed  of  men  who  had  been  associated  with  him  for  3E  years 
and  more  got  together  two. or  three  weeks  ago  and  formed 
an  Association  called  "Edison  Pioneers".  It  was  my  good 
fortune  to  be  one,  as  this  year  I  comulete  37  years  asso¬ 
ciation  with  him.  On  Mr.  Edison's  birthday,  43  of  us  met 
at  Luncheon  in  Hew  fork  to  celebrate  the  occasion  and  I 
can  tell  you  it  was  a  very  pleasant  occasion  and  we  fellows 
who  had  been  friends  for  so  many  years  enjoyed  it  greatly. 

We  sent  Mr.  Edison  a  telegram  signed  by  all  of  us. 

I  am  glad  to  learn  that  you  are  all  fixed  up 
with  such  pleasant  quarters,  and  also  that  your  lot  is 
cast  with  such  a  fine  lot  of  men.  I  have  a  letter  from 
Mr.  Hanfora  this  morning  in  which  he  tells  me  some  of  the 
interesting  things  that  have  been  happening  of  late.  I 
am  hoping  to  hear  some  good  news  concerning  your  more 
recent  tests. 

We  have  had  two  or  three  days  respite  from  zero 
weather.  Snow,  or  to  speak  more  correctly,  ice,  is  melt¬ 
ing  on  the  streets,  and  if  the  present  mild  weather  con¬ 
tinues,  wo  shall  be  having' clear  roads  in  a  few  days,  - 
a  consummation  to  be  devotedly  wisheo  for.  It  iB  a  great

Honorable  Josephus  Daniels, 
Secretary  of  the  Wavy, 
Washington,  b.  0. 

iiy  dear  Mr.  Seorotnry: 

I  have  been  experimenting  on  launching  oollision  mats  to 
save  cargo  boats  after  explosion  of  torpedo.  Be  oon  do  it 
within  twelve  seoonds.  X  am  building  a  roughmodel  of  a  cargo 
boat  on  a  scale  of  1  in  25  for  easo  in  arranging  ton  oollision 
mats  on  each  side  of  boat,  each  mat  40  feet  long  and  35  feet 
deep,  rolled  up  on  a  six-inch  pipe,  any  one  of  whioh  can  be 
launched  in  15  seoonds  so  as  to  fully  cover  the  hole.  These 
mats  are  to  bo  rolled  up  end  placed  16  feet  away  from  s id os 
of  boat  when  not  in  use,  so  the  explosion  will  not  affect  any 
of  them  and  they  will  not  interfere  with  anything  or  with  the 
launching  of  the  regular  life  boats.  I  was  surprised  to  know 
that  oil  the  officers  here  are  unanimous  in  believing  this 
scheme  will  work. 

So  far  the  kite  rudder  works  fine;  I  am  making  several 
so  as  to  tost  on  the  DOLPHill  when  she  returns. 

With  the  towed  ’phone,  the  kite  rudders  and 
mats,  we  should  increase  the  difficulties  of  the 
sinking  our  boats. 

Germans  in 

These  are  nil  attachments  that  cost  little,  require 
change  in  ships  and  are  easily  operated.  • 

Very  truly  yours.

February  26,  1518. 

Hr.  Thorm s  A.  Sdison, 
Havel  Station, 

Key  V/est,  Fla. 

Hy  dear  Mr.  Hdison: 

Colonel  Millikan  carne  in  the  office  Tuesday  afternoon  and 
pave  me  a  ver v  interesting  account  of  the  developments  of  the  v/arli 
he  is  engaged  upon  which  I  am  sure  you  v/ill  be  interested  xn  and 
when  an  oo-oor timity  affords  I  v/ill  write  or  tell  you  in  person  as 
much  as  I" could  grasp  as  a  layman.  Some  of  the  work  he  has  been 
connected  with  lias  been  incidental  to  his  ov/n  particulci  ocope 
and  while  he  did  not  hesitate  to  talk  frankly  about  it  for  your 
information,  1  gathered  that  he  preferred  I  should  not  main  a 
written  report  on  the  subject  it  having  to  do  v/ith  new  types  ol 
mines  uarticularly  the  magnetic  mine,  this  work  having  oeen  done 
for  the  Ordnance  Department  and  not  for  the  Signal  Corps^with 
vjhi  oh  I:  ill  ikon  is  associated.  They  are  agreed  with  you  the.  u  die 
magnetic  type  is  not  useful  for  some  purposes  hut  developments 
are  progressing  which  will  be  advantageous. 

Several  visual  signal  apparatus  have  been  developed  with 
which  they  are  highly  pleased.  I  am  keeping  memoranda  of  the  con- 
versationswith  Colonel  Millikan  which  may  he  of  interest  to  you 
when  you  return  or  earlier  should  your  work  approach  these  lines. 

As  I  wired  you  yesterday  X  called  on  Food  Director  Hoover  and 
handed  him  a  cony  of '  your  Hurley  telegram  of  February  2Srd  which 
he  said  he  would  refer  to  the  men  handling  the  sugar  question. 

I  had  been  on  Hr.  Hurley's  trail  and  just  after  seeing  ir. 
Hoover  learned  of  his  return  to  Hashing ton  and  went  down  and  de¬ 
livered  a  cony  to  him.  He  lad  only  a  few  hours  before  received 
the  or  iginal* relayed  message  and  was  therefore  familiar  with  the 
subject  and  in  my  oresenee  sent  sord  to  Hr.  Carry,  the  Director 
of  Ooerations  of  the  Shipping  Board,  to  send  a  man  down  to  inves¬ 
tigate  the  situation  as  you  suggested.  Since  the  telegram  first 
came  into  my  hands  I  lave  made  some  little  investigation  on  my  ov/n 
hook  which  may  be  of  interest.  Tlie  difficulty  of  using  wooden 
shins  of  more  than  five  years  age  is  that  insnranee  can  not  be  ob¬ 
tained  on  oh  in  cargoes  in  such  bottoms.  Bilge  water,  it  seems, 

is  bound  to  come  through  and  coming  in  contact  v/ith  the  lowest 
tiers  of  sugar  v/ill  cause  a  rapid  malting  from  the  bottom  upwards. 
For  that  reason  sugar  is  generally  carried  only  in  steel  shins  or 
wooden  ships  where  this  seepage  is  next  to  impossible.  Of  course 
the  old  hulks  tlat  have  been  turned  into  barges  are  very  useful 
for  cargo  such  as  lumber  and  coal  where  the  interference  of  v/ater 
does  not  damage  the  cargo. 


I  did  not  have  tiire  ,  or  rather,  Ur .  Hurley  did  not  have  time 
for  me  to  male  any  comments  on  your  telegram  end  it  would  not  have 
been  appropriate  for  me  to  do  so  anyway.  In  case  his  order  which 
was  given  to  send  a  man  down  should  be  intercepted  it  will  be  be¬ 
cause  the  Board  or  some  subordinate  assumes  the  conclusion  that 
the  1,000  ton  barges  which  you  refer  to  are  of  an  age  that  would  not 
permit  insurance  on  sugar  cargoes. 

If  an  investigation  is  not  made  by  the  Shipping  Board  as  you 
suggest,  for  this  reason,and  you  know;  these  bottoms  are  capable  of 
being  used  as  you  suggest,  I  hope  you  will  bring  it  to  Ur.  Hurley's 
attention  again  or  authorize  me  to  do  so. 

The  Ship  Iroteetion  Committee,  of  which  Commissioner  Donald 
of  the  Shipping  Board  is  Chairman,  is  hard  at  work  and  a  Sub -Com¬ 
mittee,  of  which  Admiral  Winterhalter  of  the  General  Board  is  Sen¬ 
ior  Uember,  is  also  engaged  on  the  question.  Your  letter  to  Ur. 
Daniels  of  February  23rd  on  the  subject  of  collision  mats,  I  think 
would  be  very  interesting  to  that  committee.  It  may  be  that  the 
Secretary  of  the  Eavy  will  so  refer  it  but  in  the  interest  of  quick 
action  I  wish  that  a  copy  could  be  sent  to  Commissioner  Donald. 

The  weather  here  lias  been  delightful  this  week  and  I  hope 
that  it  is  a  sign  of  an  early  spring.  We  will  all  be  very  glad 
to  welcome  you  back  here  again  when  you  decide  to  return. 

With  kindest  regards. 

jincerely ,

My  dear  Mr.  Edison: 

I  have  been  thinking  a  good  deal  of  late  about  the 
question  of  a  laboratory.  This  has  been  brought  prominent¬ 
ly  to  my  attention  lately  by  a  resolution  which  was  unan¬ 
imously  carried  by  the  Ilaval  Consulting  Board  at  its  last 
meeting  in  YJashington,  to  the  effect. that  a  start  on  a  lab¬ 
oratory  should  be  made  at  once  in  ’Washington. 

As  I  understand  it,  your  views  are  that  a  try-out  sta¬ 
tion  or  shop  is  needed  in  the  Havy  for  quick  production  and 
that  Hew  York  is  the  be3t  market  for  labor  and  material  in 
such  an  establishment.  In  this  I  agree  with  you,  but  what 
seems  to  me  to  be  rather  urgent  just  now  is  that  we  should 
have  an  office  dovm  near  the  river  somewhere  in  Washington 
to  which  might  be  attached  a  laboratory  for  experimental  and 
research  work.  This  would  be  useful  in  trying  out  some  of 
the  devicoB  and  suggestions  made  to  the  Ilavy  Department. 

As  we  have  the  Bureau  of  Standards  and  the  Bureau  of 
Hines  here  and  the  Indian  Head  Works  I  feel  that  right  here 
under  our  noses  we  might  do  a  great  deal  of  useful  work  during 
the  war,  and  possibly  after  the  war  the  question  of  a  manu¬ 
facturing  establishment  might  be  decided  either  as  an  exten¬ 
sion  of  this  laboratory  or  as  an  independent  plant  located 
somewhere  else. 

The  members  of  the  Haval  Consulting  Board  are  pressing 
me  from  time  to  time  to  do  something.  They  say  that  there  is 
a  dire  necessity  that  some  notion  be  taken  and  some  plaoe  be 
provided  at  an  early  date.  I  have  hesitated  because  I  want 
your  full  co-operation  in  everything  done  in  this  matter,  and 
I  am  writing  you  now  to  ask  if  you  will  not  agree  to  the  plan 
as  outlined  in  this  letter,  in  this  way  making  the  recommenda¬ 
tion  of  the  Haval  Consulting  Board  unanimous  by  the  vote  of 
its  President,  so  that  I  may  go  ahead. 

I  look  upon  this  as  a  very  important  and  a  very  ^gont

Assistant  to  Ur.  Edison,

Orange,  Hev;  Jersey. 

Bear  Ur.  Ueadoworoft: 

Thank  you  for  your  letter  of  the  28th  ult. 

Vie  will  communicate  with  Ur.  Uallory  very  shortly  as 
he  no  doubt  has  information  of  value  to  us. 

In  our  investigation  of  cellular  aggregates, 
we  propose  to  include  tests  of  concrete  cylinders  made 
up  with  the  metal  tubes  similar  to  the  ones  used  in  the 
Edison  battery.  It  is  necessary,  however,  to  eliminate 
the  perforations  and  use  heavier  gauge  metal. 

May  wo  call  upon  you  later  for  a  snail 
quantity  of  this  material  for  our  tests? 

.  Very  truly  yours. 

Concrete  Engineer,  Bepartment  of 
Concrete  Ship  Construction.

Honorable  Josephus  Daniels, 
Seoretary  of  the  Havy, 
Washington,  D.  C, 

In  reply  to  yours  of  Uaroh  lBt  regarding  laboratory, 
permit  me  to  say  that  my  whole  experience,  covering  a  period 
of  over  fifty-two  years,  sixteen  to  eighteen  hours  daily,  in 
over  fifty  different  branohes  of  business,  xs  dead  against 
having  a  oonstruoting  laboratory  at  either  Annapolis  or 
Washington.  The  very  heart  of  suoh  a  laboratory  is  rapid 
constriction,  and  there  is  no  plaoe  in  this  country  where 
this  can  be  done  successfully  exoopt  within  one  hour's  journey 
of  liew  York  City,  the  market  from  which  everything  oan  be 
obtained  quiokly. 

There  is  no  ob  j  eotion— ana  in  fact  it  is  the  right  thing 
to  do— to  having  the  executive  and  planning  office  at  Washington 
whioh  has  the  authority,  the  data  ana  the  money  ana  where  the 
plans  foul*  be  all  worked  out.  But  the  moment  the  blue  prints 
are  ready  for  reduction  to  a  machine  Washington  -would  bo  a 
disaster  for  the  constructing  shop  to  be  there,  wnere  weeks 
would  be  wasted  in  getting  material. 

There  is  no  analogy  between  the  Bureau  of  Standards  and 
Mines.  The  proposed  laboratory  is  to  build  anything  from 
a  submarine  to  a  microscope  and  is  not  a  research  laboratory, 
it  is  s  oonstruoting  laboratory— more  properly  a  universal 
machine  shop-whose^speoialty  is  rapid  oonstruotion  by  special 
tools  and  system  of  working. 

Of  oourse  the  board  oan  do  what  in  their  judgment  they 
think  best,  but  they  cannot  expeot  me  to  agree  to  reoommena 
what  X  firmly  believe  will  be  a  failure  to  give  rapid 
production.  I  am  so  deaf  that  X  have  seldom  attended  meetings 
of  this  consulting  board  ana  am  so  entirely  out  of  touch  with 
it  that  it  seems  to  be  a  speoies  of  deception  for  me  to 
oontinue  as  its  head,  so  I  think  I  had  bettor  disconnect  and 
work  direot  for  the  Davy,  the  board  elooting  a  young  and 
agressive  man  in  my  plaoe. 

Very  truly  yours.

My  dear  Mr.  Edison: 

I  have  your  letter  explaining  that  you  are 
experimenting  on  launching  collision  mats  to  save 
cargo  boats  after  explosion  of  torpedo.  I  am 
looking  forv/ard  with  great  interest  to  completion 
of  these  experiments.

Thank m,  vou  for  your  memorandum  ox  i'eoruu-y  £X» 
two  -,reut  difficulties  ste-na  in  tbs  v.ay  of  applying,  any  outsiae 
plaster  to  a  merchant  ship,  namely,  reduction  of  spa  id  and  neoes 
for  docking  prior  to  its  application. 

The  idea  of  using,  buoyancy  boxes  is  ires  fr 
these  c 'ejections .  People-  nave-  turned  down  plans  to  make  snips 
uns.inka.ble  because  the  Titanic  went  down  end  because  tuare  are 
numerous  instances  of  ships  sinking  nctwixi-sxanaing  Qul-ne^'’ 
tic  ns.  In  tne  first  place,  so  far  as  the  Titanio  Is  cons. 
i3  generally  understood  that  she  went  down  be  caw  for  a  double  bottom,  and  in  many  othe: 
lid  not  save  the  snip  because  there  were  n; 
the  doors  w sr e  not  tight. 

The  Donnelly  suggestion  of  buoyancy  boxes  seems 
to  me  to  be  simply  making  a  bulkhead  idea  a  practical  one  and  apply¬ 
ing  it  to  normal  ships. 

.ea,  it

If  the  hold  of

The  Donnelly  boxes  are  attached  to  the  inner

iVe  must  not  forget, hov-iever,  that  cargo  carrying

It  has  been  estimated,  that  during  the  month  of 
January  enough  grain  went  to  the  bottom  to  make  360,000  barrels 
of  flour. 

It  has  been  estimated  that  one  ship  was  sunk 
carrying  enough  bacon  to  feed  thirty  thousand  people. 

It  has  seen  estimated  that  the  economic  lose  by 
submarines  during  the  year  1917  was  between  three  and  four  bilnon 

It  has  seen  estimated  that  about  two  million  tons 
of  food  vent  down  during  the  year  1$17* 

Ke  have  a  limited  number  of  snips*  Until  we  build 
more  those  we  have  should  be  saved. 

It  does  not  solve  the  submarine  menace  to  make 
ships  uns inks. ole,  but  it  might  enable  us  to  held  cur  own  until 
the  evil  is  destroyed,  which,  in  my  judgment,  can  never  occur 
until  either  the  nest. is  destroyed  or  the  pathway  bridged. 

I  trust  tax*  you  are  in  good  health  and  spirits  and 
that  I  may  have  the  pleasure  of  seeing  you  before  very  long.

Tour  letter  of  the  2nd  has  been  received  with  various  expense 
statements  and  checks  are  euolosed  herewith. 

As  requested  reoontly  I  wish  in  the  future,  if  you  find  it 
will  not  annoy  Mr.  Edison  to  do  so,  that  you  would  have  him  0.  K.  the 
expense  aooounts  before  coming  to  me.  I  have  passed  them  into  ay  files 
without  this  approval  feeling  sure  that  they  were  correot  as  rendered  by 
you,  but  in  case  of  an  audit  of  the  aooount'it  would  be  muoh  better  to  have 
Mr.  Edison’s  0.  K.  on  each  account.  If  Mr.  Edison  does  not  objeot  to 
signing  the  aocounte  I  should  like  to  have  tho  other  boys  secure  his  0.  K. 

^  ^  _ _ _  a _ a  oheok  on  the  Private  funds  of  Mr.  Edison  for 

$7.18  to  oover  expenditures  made  for  Mr.  Edison’s  jb  rsonal  aooount.  This 
aooount  also  you  did  not  have  0.  K’d  by  Mr.  Edison.  I  trust  you  will 

have  similar  accounts  0.  K»d  by  him  la  tho  future.  You  state  that  Mr. 

Edison  has  given  you  2100.  to  expend  for  him  for  personal  ItemB.  I 
assume,  however,  that  the  §7.13  being  remitted  to  you  was  not  expended 
out  of  this  fund,  I  assume,  of  course,  that  it  was  Mr.  Edison’s  idea 
that  you  would  account  direot  to  him  for  cay  expenditures  from  thiB  fund  of 
$100.  for  personal  expenditures. 

While  neither  yourself  nor  Hr.  Wolf  has  0.  K’d  the  hill  from 
tho  Hotel  Powhatan,  from  the  faat  that  you  have  sent  it  to  me  and  referred 
to  it  in  your  letter  I  assume  that  it  1b  oorreot  and  em  sending  them  a  oheok. 

Tour  expense  aooounts  do  not  show  the  shop  orders  which  should  be 
oharged  and  we  are  charging  tho  amounts  to  shop  order  6699.  If  this  is 
not  oorreot  please  advise, and  will  you  not  in  future  kindly  mark  tho  number 
on  tho  aooounts.  You  are  bo  far  away  from  us  that  wo  oan  not  keep  in 
touch  with  tho  work  you  are  doing  and  have  to  depend  upon  you  for  the

My  dear  Mr.  Shaffner: 

Let  me  thank  you  for  your  favor 
of  the  3d  instant  enclosing  the  hill  from  the  Western 
Electric  Co.,  which  you  have  O.K.  d.  I  will  turn  it 
over  to  Mr.  Kellow  for  payment  if  I  find  from  Mr  .Wold 
that  the  price  is  right  for  the  pair  of  head  receivers. 

Yesterday  I  received  your  telegram  asking  us 
to  make  and  ship  as  soon  as  possible  two  copper  mode?-8 
the  same  as  before,  and  send  one  down  to  youjby  Soutnern 
Express  as  soon  as  completed.  •‘■here  must  be  some 
German  sharks  around  your  waters,  and  they  are  on  to 
your  game.  Perhaps  you  had  better  attach  some  hooks 
to  thl  next  lot  and  put  the  fish-Boche  out; of  business. 

I  regret  very  much,  indeed,  to  learn  that  you 
are  having  such  a  sorry  experience  in  regard  to  the 
persons  you  name.  This  is  certainly  very  discouraging 
and  troublesome  for  you,  but  I  have  the  greatest  faith 
in  your  ability  to  overcome  these  obstacles  and  to  push 
things  to  a  successful  completion  in  spite  of  them  all. 

I  am  glad  to  learn  that  all  your  material 
has  c  ome  to  hand  at  last,  and  shall  hope  to  make  your 
list  entirely  complete  by  sending  you  the  .two  copper 
models  at  an  early  date.  ;

Hr.  Thomas  A.  Edison, 
Report  on  Order  #5013:- 

After  determining  the  hast  arrangement  of  coils  for  the  use  of  the 
amplifier  under  the  condition  that  obtain  with  the  Range  Finder,  we 
secured  the  necessary  apparatus  and  equipped  all  three  stations  with 

Introduction  of  the  amplifier  has  greatly  increased  the  difficulties 
of  determining  the  exact  starting  point  of  the  shot.  Even  comparatively 
light  looal  noises  are  amplified  to  such  an  extent  as  to  make  a  pronounced 
record  and  the  vibrations  of  the  horn  by  the  foroe  of  the  wind  will  produce 
a  record  difficult  to  distinguish  from  that  of  the  shot. 

The  wind  velocities  have  been  exceptionally  severe  lately  in  fact,  in 
some  oases  the  towers  Which  we  considered  securely  anohored  were  blown  over 
but  we  believe  we  have  taken  care  of  this  by  re-inforcing  the  towers  mount¬ 
ing  the  transmitter  in  a  sound  insulated  box  dose  to  the  ground  and 
conducting  the  sound  from  the  horn  to  the  transmitter  by  means  of  rubber 
tubing  (garden  hose). 

When  we  have  been  able  to  get  records  that  wo  could  read  satisfactorily 
we  obtain  as  great  a  degree  of  accuracy  as  was  reached  without  the  amplifier 
and  of  course  over  a  greater  distance  as  indicated  by  the  following  three 
records  we  have  just  made.

Pear  Mr.  Edison: 

You  will  remember  that  you  gave  us  photo¬ 
graphs  of  a  Double-Trumpet  Sound-locating  Apparatus  to 
forward  to  the  Board  of  Invention  and  Research. 

I  enclose  herewith  photographs  of  two  patterns 
of  four-trumpet  apparatus  for  locating  aircraft  in  altitude 
and  azimuth. 

In  one  pattern  the  azimuth  trumpets  are  3'  6" 
in  diameter  at  the  mouth.  In  the  other,  all  four  trumpets  are 
1'  6"  in  diameter.  It  will  be  observed  that  sights  are 
fitted  to  facilitate  the  direct  control  of  searchlights  by 
bringing  the  apparent  end  of  the  beam  onto  the  foresight  when 
aircraft  are  being  followed  acoustically. 

I  forward  these  photographs  in  the  hope  that  they 
may  be  of  interest  to  you. 

Yours  very  sincerely,

My  dear  Mr.  Shaffnar:  . 

I  received  your' letter  of  the 
‘11th  instant  in  regard  to  some  hand  'phones  that  you 
wanted  to  have  made  up  hy  the  Western  Electric  Co. 

At  the  same  time  I  have  received  your  telegram  of 
yesterday,  and  have  sent  you  the  following  Day  letter 
today.  This  explains  itself. 

'Received  your  letter  eleventh 
and  telegram  of  thirteenth  regarding 
Bell  receivers.  As  I  understand  it, 
your  telegram  supersedes  your  letter 
and  you  will  not  want  the  200  and  350 
ohm  receivers.  Have  ordered  six  500. 

Tell  Mr.  Edison  his  condensers,  coils  and 
wire  go  express  today." 

You  will  see  the  uncertainty  that  I  feel  about 
it,  but  possibly  I  may  hear  from  you  by  telegraph  before 
you  receive  this  letter. 

With  kindest  regards  to  you,  I  remain,

Dear  Hr.  Edison: 

You  will  recall  that  sometime  ago 
you  suggested  to  me  the  idea  of  placing  motive 
power  in  sailing  vessels.  Evidently  that  sug¬ 
gestion  which  was  given  some  publicity  has  aroused 
the  interest  of  Hr.  William  T.  Cutter,  whose  let¬ 
ter  to  Senator  Brandegee  is  herewith  attached. 

I  am  sending  you  the  correspondence  for  your  in¬ 



With  kind  regards,  X  am. 

Sincerely  yours,'

United  States  Navy  Yard, 

NEW  YORK.  N.  Y. 

Far  eh  19,  1918. 

Isiy  dear  Ldc .  Edison; 

I  have  delayed  answer ins  your  letter  in  regard  to 
the  jwdro^-en  detector  in  the  hope  that  I  would  receive 
a  report  of  tests  from  the  Bureau  of  Standards  to  whom 
I  forwarded  a  Eurrell  instrument  for  test  quite  a  wnile 
ago.  '.Then  X  get  tnis  report  I  will  send  you  a  copy. 

The  <ms  detector  which  we  are  manufacturing  and 
issuing  was" developed  hy  the  Bureau  of  Standards .Re¬ 
peated  tests  made  at  this  yard  with  mixtuies  of  k-.own 
hydrogen  content  indicate  that  tliese  detectois  are 
accurate  to  about  l/4  of  l£,  whica  I  th^issuf^; 
ciently  accurate  for  our  purposes  as  we  are  not  certain 
wi thin^the se  limits  as  to  when  the  mixuure  reacnes  the 
danger  point. 

Our  tests  on  Burrell  tubes  have  indicated  their 
accuracy  to  about  l/2  of  1 £  but  1  am  awaiting  a  report 
from  the  Bureau  of  Standards  on  the  accuiacy  of  these 
tubes  which  we  used  as  a  check  on  our  automatic  detectors. 
They  are  rugged  and  portable . 

The  Sperry  type  has  not  been  accepted  due  to  in¬ 
accuracy  as  found  on  our  tests. 

The  instrument  submitted  by  you  was  f ounu  to  ce 
very  accurate  on  our  tests  and  its  great  accurary  ma-e 
■it  valuable  as  a  laboratory  standard,  but  I  thin.,  it  is 
doubtful^ if  the  average  enlisted  man  could  operate  success¬ 
fully  this  instrument  on  a  submarine. 

HP.  Feadoworoft  is  mistaken  in  supposing  that  X  left 
all  this  to  subordinates  as  I  was  in  touch  with  the  main 
features  of  the  different  instruments  tested.. 

As  you  know,  the  men  on  submarines  may  possibly  be 
careless  or  neglectful  in  taking  readings  with  an  instru¬ 
ment  that  requires  a  special  operation  for  the  purpose, 
whilov'Sth  one  that  is*  continuous  reading  they  would  be 
more  apt  to  know  the  percentage  of  gas  m  tneir  boatand 
if  in  addition  to  having  the  continuous  reading,  theie  is 


a  "bell  tiiat  rings  when  the  assumed  danger  point  is 
reached,  I  think  the  people  on  the  boathave  teen  pro¬ 
vided  with  means  to  prevent  explosion  so  fai  as  vnat 
is  possible. 

She  conditions  may  he  compared  to  a  steam  boiler 
under  uressure,  -  if  the  firemen  were  expected  to  attach 
ail  instrument  and  go  through  an  operation  to  find  out 
tlip  “boiler  oressure  at  any  tune  end  no  saiety  valve  pi o 
vided  I  should  exoect  explosions  to  be  common;  but 
as  there  is  urovided  a  continuous  reading  pressure  gauge

Mr.  Thomas  A.  Edison, 

Edison  Laboratory, 

Orange,  N.  J. 

My  dear  Mr.  Edison: 

At  the  last  meeting  of  the  Board  on  March  16th 
it  was  agreed  that  each  member  who  was  so  disposed  should 
individually  express  to  the  Seoretary  of  the  Navy  his 
views  as  to;  the  need  for  a  great  number  of  additional 
large,  seaworthy  and  fast  submarine  chasers.  Some  of 
our  members  have  already  written  or  telegraphed  to  the 
Seoretary  advocating  the  immediate  construction  of  250  of 
suoh  boats.  It  seems  important  that  as  much  pressure 
as  possible  should  be  brought  to  bear  on  the  Navy  Department, 
and  with  the  thought  that  you  may  find  in  it  some  information 
which  you  might  make  use  of  in  writing  or  telegraphing  to 
the  Secretary,  I  am  sending  enolosed  a  oopy  of  a  letter 
which  I  wrote  him  under  date  of  March  18th,  also  a  oopy  of

My  dear  Mr.  Hanford: 

I  have  to  acknowledge  receipt  of  your  letter  of  March 
21,  19X8,  addressed  tome  at  Mr.  Edison's  direction,  with 
reference  to  the  vessels  bringing  lumber  and  other  commo¬ 
dities  to  Cuba  and  returning  light  to  the  United  States. 

You  may  rest  assured  that  I  shall  do  everything  in  my 
power  to  have  this  tonnage  diverted  to  the  carrying  of  sugar 
in  order  to  relieve  the  threatened  congestion  at  some  of  the 
Cuban  ports,  and  I  am  glad  that  you  have  referred  inquiring 
ship  owners  to  me .

Dear  Mir.  Meadowcroft: 

I  received  an  inquiry  this  afternoon  from  the  Office  of 
Naval  Intelligence  as  to  a  chemist  named  Silver.  As  I  la 
freauent  inquiries  as  to  who  is  connected  or  working  with 
the^Navla  Consulting  Board  do  you  not  think  it  advisable  to 
furnish  me  with  a  list  of  the  names  of  those  working  in 
connection  with  or  under  Mr .  Edison? 

Hotline  everything  is  going  well  with  you  and  if  corre¬ 
spondence  with  Mr.  Edison  is  not  going  satisfactory  please 
inform  me  personally. 

In  locating  the  quarters  in  the  new  Building  to  he 
erected  for  the  Nayy  Department  I  see  they have  included  a 
rnnrn  for  Mr  Edison  adjacent  to  the  General  Board.  ^ad 
already  P^vided  for  him  in  the  Naval  Constating  Board  quarters 


he  could  probably  receive  more  personal  attention. 

Will  you  take  this  up  with  him  or

March  29th,  1918. 

Ur.  Thomas  A.  Edison, 
Key  West,  Florida. 

My  dear  Mr.  Edison: - 

On  arriving  here  last  week  I  at  onoe  went  to  Mr.  Langley  and 
asked  for  his  assistance  to  familiarize  him  with  the  whole  situation. 

He  accompanied  me  to  the  Bishop  Gutta  Pescha  Company  and  went  over  the 
situation  with  Hr.  Held,  the  Manager  and  Vice  President  of  the  fins. 

They  had  about  half  made  2  pieces  of  concentric  cable,  eaoh 
piece  2,000  ft.  in  length,  the  outer  conductor  is  of  copper  in  place 
of  steel  as  in  the  former  oable.  The  outer  covering  is  of  a  very  high 
quality  and  will  be  the  best  for  the  work.  This  will  add  to  the  flex¬ 
ibility  of  the  oable  and  wi  11  not  break  if  properly  protected  at  the 
weak  point.  This  cable  he  expects  to  ship  the  first  of  the  week.  He  is 
also  making  up  the  200  Ft.  of  very  flexible  cable  which  you  desired.  It 
is  made  up  with  19  strands  of  #32  steel,  with  concentric  winding  with 
oopper  highly  Insulated  and  to  be  over  1.8  inoh  in  diameter. 

In  reply  to  your  telegram  which  is  as  follows: - 

"Two  single  cables  twisted  together  acts  best,  a  single  strand 
breaks  at  three  hundred  pounds,  has  twice  strength  necessary,  have  four 
thousand  feet  single  cable  made  with  oopper  and  steel  wires  half  the  weight, 
but  keep  rubber  same  thickness  braid  and  wax  we  will  twist  cables  here." 

will  say  Mr.  Reid  has  finally  found  material  to  make  a  oable  which  he  believes 
to  be  ideal  for  your  work.  He  found  some  "Airoplane  strand."  This  strand 
is  of  7  #28  B  &  3  very  high  grade  steel  with  tensil  strength  of  18S  lbs. 
each  strand.  When  this  oable  is  completed  it  will  be  about  the  same  diameter 
as  the  cable  you  are  now  using. 

We  hope  that  this  will  be  satisfactory. 

Mr.  Langley  and  myself  have  designed  what  we  consider  a  very  well 
insulated  "magnetophone"  and  two  of  than  are  being  made  up.  Expeot  to  ship 
than  about  next  week.  '  It  is  a  hand  phone  made  over  and  enclosed  in  hard 
rubber  and  I  believe  it  would  be  impossible  for  the  Insulation  to  break  down 

Mr.  T.  A.  Edison  -2- 

provlding  there  is  great  oare  used  in  assembling  it.  Drawings  will  be 
forwarded  to  you  the  first  of  the  week.  He  is  also  making  up  a  telephone 
of  the  hand  phone  type  which  is  said  to  be  a  little  more  efficient  and  will 
be  practically  impossible  to  break  the  insulation  down  on  it  if  ordinary 
oare  is  used  in  handling  it.  It  is  very  difficult  to  get  in  the  open  market 
hard  rubber  with  high  insulating  properties.  It  is  usually  made  from  scraps 
which  contain  metal  and  all  kinds  of  conducting  material.  V/B  find  that 
to  get  rubber  suitable  for  the  high  class  of  this  work,  it  will  be  necessary 
to  have  the  rubber  made  up  especially  for  that  pui-pose.  . 

Mr.  Langley  is  go'ng  to  push  this  right  alo  ng  and  will  send  them 
down  just  as  soon  as  possible.  V/e  will  not  assemble  them  entirely  because 
we  think  it  best  for  some  careful  man  to  assemble  them  there,  then  he  will 
understand  the  mechanism  and  how  to  handle  them.  I  want  to  caution  you 
that  great  care  must  be  used  to  get  results  with  these  2  instruments  using 
carefully  applied  the  black  cable  wax  you  have  there  on  all  of  the  threads 
and  joints  that  you  expect  to  take  apart  and  the  black  armature  varnish  In 
sealing  up  around  the  diaphragm.  Mr.  Langley  thinks  that  the  clear  varnish 
we  are  sending  you  will  answer  better  than  the  ordinary  black  varnish  we 
got  from  the  Street  Hallway  Company  when  I  was  there. 

iVe  had  the  magnets  on  these  2  types  of  instruments  re-wound  so  that 
they  will  be  about  what  is  necessary  for  the  primary  winding  in  the  audion

I  am  leaving  here  tomorrow  for  my  home,  6107  Kimbark  Avenue,  Chicago,

1.  In  connection  with  your  statement  of  Pobruury  28th, 
some  explanation  is  doairad  of  your  charges  "Overhoad,  50,'J  on 
maohino  labor  and  25%  on  supervision,  total  $535.48."  Tide 
seems  to  bo  rathor  an  ext x*aordi nary  item  for  construction  imft  . 
in  which  tho  machine  labor  alone  amounted  to  the  sum  of  $875.08, 
and  supervision  and  drafting:  $318. CO,  a  total  of  $1194.48,  which 
total  would  seem  to  bo  amply  sufficient  for  the  v;ork  produced. 

2.  In  this  oonnootion,  it  is  desired  that  in  your 
reply  you  include  a  copy  of  tho  letter  of  Dr.  Yandoll  Henderson, 
authorizing  you  to  do  this  work.  Tho  following  quotation  from 
tho  minutos  of  tho  Nodical  Research  Board  bears  on  the  above 
statement : 

"In  a  free  discussion  of  the  bill  by  tho  Board, 
it  wan  agreed  that  the  qjinrges  were  exceeding¬ 
ly  exorbitant."

Lly  Dear  Mr.  Edison:-  uO 

Lly  Dear  Mr.  jsarson:-  U4>t' 

Upon  receipt  ^Siietlfersometime  J 

since  from  Mr.  Shaffner  advising  us  that  the  cables 
which  we  furnished  you  for  experimental  work  has  not 
proved  satisfactory.  We  entered  a  shop  order  for  two 
more  cables  similiar  too  the  ones  we  had  furnished, but 
arranged  to  substitute  copper  wiiei  for  the  outside 
conductor  instead  of  the  tinned  steeled  wire,  we  also 
had  omitted  the  wind  of  cotton  over  the  outside  conductor 
which  may  have  been  the  cause  of  the  trouble  which  you  had. 

We  are  shipping  you  today  one  of  these 
cableB.  After  having  this  cable  submerged  in  salt  water  for 
24  hours  we  connected  the  center  conductor  to  ground  and 
applied  1,000  volts  for  5  minutes,  we  then  tested  the 
insulating  resistance  and  found  that  the  insulation  from 
the  outside  conductor  to  ground  gave  2770  megs  per  mile, 
we  therefore  believe  that  this  cable  should  work  satisfactory 
and  would  like  very  much  to  have  you  try  it  out. 

The  other  cable  referred  to  is  well 
along  and  will  probably  be  ready  for  shipment  within  the 
next  week. 

Hoping  that  y<Su  have  better  luck  with 
these  two  cables  than  you  did  with  those  we  formerly  made 
we  remain.

Tho  exporimonte  which  Hr.  Edison  has  been  conducting 
for  tho  Govornmont,  as  aforesaid,  cannot  be  classified  as- coming 
undor  the  head  of  Industrial  Production,  as  Ur'.  Edison  does  not

Mr.  Thomas  A.  Edison, 

Key  West,  Fla. 

My  dear  Mr.  Edison 

I  thank  you  very  much  for  your  letter  of  April 


It  is  somewhat  comforting  for  me  to  know  that 
yoxi  too  have  been  up  against  the  same  Bureau  chiefs  who 
have  been  blocking  progress  in  the  anti-submarine  work. 
Instead  of  their  helping  to  win  the  war,  they  are  the 
very  men  who,  in  ray  opinion,  are  most  responsible  for  the 
continuance  of  the  war. 

I  am  satisfied,  and  anyone  else  who  had  used 
the  latest  detectors  would  be  satisfied,  that  their  adop¬ 
tion  on  a  large  scale  would  put  an  end  to  the  submarine, 
and  that  means  an  end  to  the  war,  but  the  old  fogies  are 
not  willing  to  admit  that  the  Navy  needs  any  help  from 
outside.  The  public  does  not  know  this,  'and  it  wouldn’t 
believe  it  unlesB  the  statement  were  mad,e  by  you,  and  I 
hope  that  before  long  you  will  make  a  public  statement. 

If  this  were  done,  it  would  probably  lead  to  the  retire¬ 
ment  of  the  majority  of  the  present  Bureau  chiefs  and 
the  substitution  of  younger  men  and  possibly  some  civil¬ 
ians,  for  even  the  young  men  in  the  Navy  are,  as  a  class, 
very  narrow-minded.  But  there  will  not  be  any  improve¬ 
ment  until  you  explode. 

Sinoerely  yours.

Information  at  Grand  Central  Station  to  join  us. 

2.  I  will  have  two  oars  at  your  house  Saturday  morning

will  follow  in  oase  of  puncture.  We  will  go  to  the  Grand  Cen¬ 
tral  Station,  and  I  will  take  you  to  the  dining  room.  I  will 
then  go  to  the  Bureau  of  Information  and  await  the  Secretary, 
escorting  him  to  our  table. 

3.  I  have  arranged  for  transportation  for  yourself,  Sec¬

tests  on  some  devioe  whibh  Lindon  Bates,  Chief  Engr.  of  Submar¬

me  to  New  London,  and  I  am  arranging  to  have  a  conference  with 
the  men  who  have  the  submarine  apparatus  in  charge  on  Tuesday 
evening.  I  will  spend  Wednesday  conducting  tests  on  the  appar¬ 
atus  and  will  work  out  an  itinerary  for  Saturday.  I  will  re¬ 
turn  to  Hew  York  not  later  than  Thursday  afternoon  and  will  re¬ 
port  to  you  in  detail.  I  will  then  remain  in  Orange  Thursday 
and  Friday,  to  go  with  you.:to  New  York  Saturday  morning.

have  graphic  illustrations  to  embody  in  such  report  as  you  may 
make  to  the  Secretary  subsequent  to  your  tests  of  the  devioe.

President,  Naval  Constating  Board, 

The  Service  Bureau  (created  by  Executive  Order  of  March  19, 
1918)  of  the  Committee  on  Public  Information,  has  opened  an  of¬ 
fice  at  15th  and  G  Street,  N.  W.,  in  the  rooms  formerly  occupied 
by  the  uptown  ticket  officeB  of  the  Pennsylvania  Railroad. 

This  Bureau  maintains  an  up-to-date  card  index  directory  of 
all  Government  Departments,  covering  officials,  function  and  loca¬ 
tion.  It  serves  as  a  source  of  information  for  all  men  coming  to 
Washington  in  connection  with  Government  business;  for  all  Gov- 
ornment  Officials!  and,  as  far  as  possible,  as  an  inter-departmenl 
olearing  house. 

Vie  desire  to  serve  all  Government  Departments  in  every  way 
possible,  and  will  be  glad  to  have  you  refer  to  us,  whenever  you 
are  in  doubt  as  to  their  proper  destination,  all  parties  coming  to 
you  on  Government  business  other  than  that  belonging  to  your  De¬ 
partments!  and  to  forward  to  us  all  letters  of  inquiry  regarding 
Government  business,  which  do  not  belong  in  your  Department,  and 
about  the  routing  of  which  there  is  unoertalinity.  '

Chaser  remained  still. 

Submarine  0  2  was  instructed  to  run  from  Chaser  in  a  straight  course 

at  a  speed  of  4  knots  per  hour. 

(Speed  of  G  2  submerged  is  10  knots  at  360  of  motors) 

Calculated  E.  P.  M.  at  4  knots  should  be  144)

At  times  the  intensity  would  die  down  for  a  brief  period. 

Can't  explain  the  reason  for  this  variation  in  intensity. 

The  apparatus  was  very  sensitive  to  direction,  a  movement  of  10° 
on  scale  would  diminish  Bound  considerable. 

People  walking  on  deck  directly  over  apparatus  would  interfere  at 

times . 

There  was  also  an  occasional  hissing  sound  in  right  ear-tube,  due 
probably  to  some  fault  in  the  tube  or  button  construction. 

At  times  would  lose  sound,  but  by  adjusting  instrument  would  pick 
it  up  again  at  another  bearing. 

The  Chaser  being  free  to  drift  in  any  direction  accounts  for  this 
bearing  change. 

The  Character  of  the  submarine  noise  consists  of  three  distinct 
beats  to  the  revolution.  One  beat  being  of  greater  intensity  and  of 
longer  duration  than  the  other  two. 

The  predominant  beat  is  accompanied  occasionally  by  a  sort  of  a 

/  • 


glub,  or  big  water  bubble  noise. 

After  listening  46'  SB”  could  just  hear  the  predominant  beat  which 
died  down  to  a  slight  cough  and  finally  turned  into  a  steady  roar.  EPM 
could  no  longer  be  oounted. 

Hearing  time  was  45'  25". 

Average  R.  P.  M.  Oounted  was  137-1/3. 

Calculated,  distance  submarine  could  be  heard  was  2.  89  nautical 
miles,  or  3.32  statute  miles,  or  5860  yards. 

Calculated  speed  of  Submarine  was  3.81  knots  per  hour,  or

Nahant,  Mass.,  May  6,  1918. 

Mr.  Thomas  A.  Edison, 

Orange,  Hew  Jersey. 

Dear  Mr.  Edison: 

Based  on  the  knowledge  we  now  have  regarding 
capabilities  of  detection  devices  and  the  conditions  of  sub¬ 
marine  operation  in  European  Waters,  there  is  no  doubt  but  that 
if  America  will  produce  and  equip  an  adequate  number  of  suit¬ 
able  submarine  chasers  the  menace  from  the  submarines  con  be 
reduced  to  a  negligible  value  and  the  future  safety  of  America’s 
interests  on  the  sea  insured.  It  is  my  opinion  that  suitable 
chasers  should  have  the  following  characteristics:  _ 

SHIP:  About  200  feet  long,  strongly  built  to  withstand  depth 

charges,  sea  worthy,  22  knot  speed,  free  from  unnecessarily 
noisy  projecting  stern  or  strakes,  provided  with  quickly 
operating  and  quiet  running  anchor  gear,  all  auxiliaries 
capable  of  being  instantly  silenced,  boiler  and  power  plant 
laid  out  for  quick  stopping  and  starting  also  to  permit 
getting  under  way  at  full  speed  in  minimum  time  on  short 
notice  after  hours  of  drifting,  main  engines  to  make 
minimum  possible  noise  while  under  way  at  all  speeds. 

ARMAMENT:  Two  guns  to  equal  or  outrange  those  on  the  submarines 
but  small  enough  to  permit  training  from  a  vessel  of  this 

size;  machine  guns;  at  least  twenty  300  lh.  or  heavier 
depth  charges  with  suitable  projectors,  and  n  denth  charge 
thrower  with  a  range  of  one  thousand  yards  for  100  lbs. 
of  T.N.T. 

DETEC TIOM  DEVICES:  Must  be  suitable  for  running,  drifting  and 
anchored  patrols,  as  well  as  for  the  chase;  the  best  forms 
of  attached  to  the  hull  devices,  overboard  drifter  sets, 
towing  listening  devices,  and  towing  contact  devices  should 
be  adopted;  existing  devices,  completely  developed,  adequate 
for  this  work  are  now  available.  Future  developments  will 
be  in  the  nature  of  refinements  and  improvements  and  it  is 
unnecessary  to  consider  them  before  undertaking  this  chaser 

C0HMUHI0ATI0H:  V/ireless  telephone  (5  miles  radius),  Wireless 
telegraph  (100  miles  radius),  special  shapes,  direction 
and  range  indicators,  truok  lights,  search-lights  with 
signal  shutter,  speaking  tubes  for  communicating  between 
devioes,  plotting  room  and  bridge;  secret  recognition 
signalling  devices,  ranging  devioes  to  permit  the  location 
of  any  ships  in  the  tactical  group  to  be  determined  by  the 
other  ships,  during  all  weather  conditions  of  day  and 
night  are  essential. 

PERSONNEL:  The  actual  destruction  of  a  submarine  requires 

quick,  snappy  action  and  too  much  emphasis  cannot  be  placed 
on  the  neoessity  of  a  high  grade,  trained  crew,  preferably 

-  3  - 

commanded  by  a  regular  Mavy  offioer  of  destroyer  training, 
with  a  second  in  command  known  as  a  hydrophone  offioer  who 
will  he  responsible  for  listening  under  chasing  conditions 
and  responsible  for  the  decisions  reached  from  the  listen¬ 
ing  results  obtained. 

-  Comments  on  Chaser  Characteristics  - 

There  is  no  reason  to  believe  that  if  the  Havy  Department 
decides  to  proceed  and  an  adequate  number  of  ships,  which  as 
you  know  should  be  at  least  a  total  of  350,  are  produced  there 
will  be  little  difficulty  in  filling  any  of  the  conditions 
outlined  above  with  the  exception  of  that  of  the  speed  of  the 
ohasers.  A  minimum  of  23  knots  is  essential  for  the  following 

The  most  frequent  contacts  with  enemy  submarines  may  be 
anticipated  at  night  while  the  chasing  patrol  is  lying  drifting 
and  sound  contact  obtained  with  an  approaching  submarine  whi o h 
is  either  bound  to  or  from  its  base  of  operations,  or  toward  a 
light  to  locate  itself  accurately  before  going  onto  a  ship  lane. 
There  are  German  submarines  now,  according  to  the  best  knowledge 
available,  having  a  surface  speed  of  17  knots  and  others  about 
to  be  put  in  service  wit;  a  surface  speed  of  20  knots.  Since- 
it  is  necessary  for  a  chasing  boat  to  either  slow  down  or  en¬ 
tirely  stop  to  listen,  and  since  these  slow  downs  or  stopB  must 
be  made  at  relatively  frequent  intervals,  an  excess  speed  over 
the  pursued  boat  is  absolutely  necessary. 

We  in  Captain  Leigh's  Party  ourselves  experienced  two 

instances  of  submarines  operating  at  perhaps  16  knots  leaving 
our  10  knbt  trawlers  and  the  helpless,  disheartening  feeling 
under  these  ciroulstances  can  be  better  imagined  than  expressed. 

It  is  obvious  that  any  Sneed  less  than  that  of  the  pursued 
submarine  will  result  in  a  similar  condition.  Houghly,  in  my 
opinion  80$  of  the  contacts  with  enemy  submarines  will  occur 
while  the  submarines  are  on  the  surface  at  night  and  under  these 
conditions  it  is  my  firm  belief  that  the  number  of  times  the 
chasing  boats  can  close  up  on  the  submarine  after  once  starting 
a  chase  will  be  about  as  follows: 

18  knot  boat  -  10$ 

20  "  "  -  60$ 

82  »  "  -  100$ 

If  we  had  18  knot  ships  a  year  ago  they  would  have  done  good 
service,  but  if  we  are  now  to  build  ships  for  chasing  submarines 
it  would  be  extremely  unwise  not  to  anticipate  the  future 
developments  of  tho  German  submarine  which  undoubtedly  v/ill  be 
in  the  direction  of  higher  speed.  Twsnty-two^knots  is  really 
the  minimum  that  should  be  considered  on  boats/already  started 
and  higher  speeds  would  be  better  if  obtainable.  In  addition 
to  the  imperative  need  of  speed  to  overtake  a  submarine  running 
on  the  surface  there  are  the  incidental  advantages  of 
first,  more  quickly  getting  to  the  point  where  a  submarine  has 
been  reported  thereby  increasing  the  chances  of  obtaining  sound 
contact  with  it  and,  second,  the  chance  that  a  submarine  seen 
on  tho  surface  during  the  late  hours  of  the  day  can  be  overhauled 

and  made  to  submerge  before  dark.  Having  once  compelled  a  sub 
marine  to  submerge  the  chances  of  destroying  it  are  greatly 

It  would  be  unwise  to  slow  up  or  change  the  Ford  program 
hut  each  succeeding  lot  of  ships  should  certainly  have  incor¬ 
porated  in  their  design  all  the  requirements  found  essential  by 
those  in  closest  contact  with  the  anti-submarine  work. 

If  we  can  supnly  you  with  any  more  specific  information 
or  be  of  use  in  any  way  in  furthering  the  chaser  program,  please 
feel  perfectly  free  to  call  upon  us.  I  am  enclosing  quotations 
from  two  letters  from  Mr.  Scott  in  London  which  give  a  little 
side  light  on  the  Admiralty's  position  and  the  possibilities  of 
the  devices.  It  should  be  born  in  mind  that  the  probable  sinking 
of  a  submarine  by  our  party,  and  by  the  three  beats  referred  to 
in  Mr.  Scott's  letter  are  X  believe  the  initial  instances  where 
three  chasing  boats  started  out  wtth  the  intention  of  hunting 
and  getting  a  submarine  and  were  successful.  This  is  a  radical 
advance  over  tho  destruction  of  submarines  by  accidental  contact 
of  destroyers,  etc.  and  if  carried  out  on  a  considerable  scale 
should  have  a  tremendous  influence  on  the  morale  of  the  German 
submarine  crews. 

Very  truly  yours,

Quotation  from  letter  from  C.  F.  Scott  to  C.  E .  Eveleth, 
dated  London,  April  5,  1918. 

"The  fourth  Hunting  Patrol  Unit  claim  to  have  destroyed 
an  enemy  submarine  off  Portland  on  March  13th,  and  the 
Admiralty  are  investigating  the  claim.  She  unit  was  equipped 
with  S.C.  C-Tubes  (now  called  Inboard  C- Tubes)  and  Hash  Fishes, 
and  was  making  a  running  and  stopping  patrol.  At  5.00  a.m. 
they  took  in  the  fish  on  H.M.T.  JOH11  CASSWELL,  and  the  "C"  tube 
listener  went  on  his  watch,  and  on  the  very  next  stop,  he  heard 
the  sound  of  a  submarine  propeller.  The  listener  with  whom  I 
later  talked,  said  that  he  gave  the  Commanding  Officer  a  bearing 
of  120°,  and  about  700  yards  distance.  The  trawler's  course  was 
changed,  the  distance  run,  and  on  the  next  stop,  he  obtained  the 
sound  at  10°.  The  other  two  trawlers  had  been  advised  that 
sound  contact  had  been  obtained  with  a  submarine,  and  they  were 
then  able  to  give  cross  bearings  with  the  Fishes,  which  permitted 
one  trawler  to  drop  depth  charges  over  the  spot  while  the  two 
other  trawlers,  which  had  given  the  bearings,  projected  depth 
oharges  over  the  same  spot.  Groat  quantities  of  oil  came  up 
and  later  trawling  cables  met  with  obstruction  at  this  spot. 

I  have  talked  with  all  tiree  Captains  of  these  three  trawlers, 
and  they  seem  to  feel  that  they  did  destroy  the  submarine". 

"IHBOAKD  C  TUBES.  A  total  of  approximately  30  trawlers 
have  been  equipped  with  this  type  of  tube". 

Quotation  from  letter  from  C.  F.  Soott  to  Dr.  W.H. Whitney 
dated  London,  April  7,  1918. 

"As  to  the  Question  of  200  ft.  chasers.  The  composite 
impression  which  X  have  formed  from  talks  vnth  British  Officers 
at  the  Admiralty  and  our  own  Kavy  people,  is  that  a  200  ft. 
chaser  built  to  stay  out  in  any  sea,  properly  gunned,  with  a 
speed  of,  let  us  say,  20  to  22  knots,  and  to  readily  silence 
all  auxiliaries  whenever  the  engines  are  shut  down  ±or  listen¬ 
ing  purposes,  would  fill  a  gap  v/hich  no  allied  craft  today  can 
fill.  The  little  110  ft.  chasers  now  being  sent  over  are 
distinctly  fair  weather  ships,  and  from  discussions  I  have  heard 
among  our  Havy  people,  they  do  not  feel  that  ships  of  this  type 
can  be  called  upon  to  stay  out  from  their  bases  for  more  than 
four  days .  One  day  steaming  to  their  patrol  area ,  two  days 
patrolling,  and  one  day  returning  to  their  base.  They  feel 
that  not  only  will  the  personnel  not  be  able  to  stay  out  longer, 
due  to  cramped  quarters,  etc.,  but  that  the  shi^s  themselves 
are  going  to  pound  themselves  to  pieces  unless  they  are  handled 
rather  gently." 

"As  to  what  devices  the  200  ft.  chasers  would  carry  is 
father  difficult  to  state  and  will  depend  entirely  on  the 
developments  tnat  may  crystallize  in  the  next  tv/o  or  three 
months" . 

"The  Admiralty  state  definite  preference  for  a  listening 
device  which  is  part  of  the  ship,  gives  direction,  and  v/hich 
•could  be  repaired  and  maintained  without  docking  the  ship, 
■^ailing  that,  a  towing  device,  rugged  in  construction,  which 
can  be  used  while  ship  still  has  headway  after  engines  have 
been  shut  down.  The  higher  the  coasting  speed  at  whicn  good 
listening  is  possible,  the  better;  especially  is  this  true 
where  devices  are  considered  for  22  knot  vessels  .

My  dear  Mr.  Secretary:- 

I  was  very  much  pleased  that  you  should  have  "one  to  Hew 
London  submarine  base  and  witnossed  the  actual  locating  of  a 
submarine  running  submerged  and  in  on  unknown  direction;  also 
that  you  have  afforded  really  ample  facilities  to  the  various 
scientific  men  to  work  out  the  problem,  and  have  given  the 
younger  officers  of  the  Havy,  like  Hepburn,  McDowell  and  Libby, 
a  chance  to  show  what  they  can  do.  /.fter  you  returned  I  went 
out  all  next  day  with  the  boats  end  verified  certain  details 
not  carried  out  in  the  test  conducted  in  your  presence. 

My  opinion  is  that  if  you  back  up  those  young  officers 
and  scientific  men,  give  them  the  kind  of  boats  they  want,  und 
do  it  quick,  thet  the  submarine  will  be  reduced  from  a  sorious 
menace  to  a  minor  annoyance. 

Yours  sincerely,

My  dear  Mr.  Secretary: 

The  Naval  Consulting  Board  would  appreciate  the  op¬

all  of  its  members,  some  of  whom  have  not  been  there,  may 
make  certain  observations  upon  anti-submarine  devices  in 
practical  operation. 

In  view  of  the  urgency  of  this  matter,  may  I  request, 
if  you  are  agreeable  to  this  plan,  that  orders  be  issued 
so  that  the  Board  may  make  its  observations  beginning  not 
later  than  Monday,  May  the  30th? 

Respectfully  yours, 

(signed)  W.L. Saunders 
Chairman,  Naval  Consulting  Board. 

As  the  Secretary  will  probably  agree  to  this  plan  I  would 
suggest  your  advising  me  at  onoe  by  telephone  if  you  would  be  able 
to  spend  Monday  at  New  London,  and  if  you  would  like  me  to  engage 

for  you  a  seat  on  the  5.10  train  leaving  New  £rkSuW  afternoon

To  the  Members  of  the  Naval  Consulting  Board: 

is  Park  Row.  New  York 


Please  "be  advised  that  the  next  meeting 
of  the  Naval  Consulting  Board  will  be  held  on 
MAY  25  1918  iQ  the  Carnegie  Institution,  Wash¬ 
ington,  D.  C. 

The  preliminary  meeting  begins  at  nine 
o'olook  and  the  formal  mooting  at  ten. 

Very 'truly  yours, 




Oyster  Bay,  H.Y.,  6/2^1918, 



My  dear  Mr.  Headowcroft : 

notwithstanding  a  heavy  down  pour  of 
rain,  I  have  made  considerable  headway  today.  Got  in  touch 
early  thiB  A.  M.  with  Mr.  Raymond  Smith.  Made  his  acquaintance 
at  the  Red  Cross  meeting  last  night  and  made  an  engagement  with 
him  for  9  A.  M.  today.  He  took  me  in  hiB  automobile  to  the 
different  places  hereinafter  mentioned.  He  was  undoubtedly 
the  man  for  me  to  see  and  has  all  the  details  of  long  Island 
property  at  hiB  fingers  end.  First  -  He  tells  me  that  the 
Center  Island  property  is  out  of  the  question. 

Ho  one  over  there  would  sell  to  any  Industrial  Enter¬ 
prise  -  that  it  is  strictly  a  residential  proposition  ana  every¬ 
thing  else  is  barred  and  any  purchaser  would  be  subject  to  the 
consent  of  the  other  owners.  I  am  going  to  inclose  one  of  his 
maps  and  you  can  see  the  full  names  of  the  owners  printed  on  the 
map.  Without  the  element  of  Commandeering  by  the  Government, 
this  property  would  be  practically  impossible. 

Second:  Che  Flat  ground  between  the  Sound  and  Bay  which 
Mr.  Edison  saw  between  the  two  old  wrecks  and  near  the  Ferry  to 
Greenwich,  Conn.,  belongs  to  the  Jones  family  who  own  a  lot  of 
property  on  long  Island  and  in  and  around  Hew  York  and  they  are 
very  hard  to  do  any  business  with.  Unreasonable  in  price,  and 
unreliable  to  do  business  with.  Mr.  Smith  said  they  would  want 
a  million  dollars  for  their  holding  of  from  50  to  75  acres.  This 
land  is  from  700  to  80u  feet  back  from  the  Channel  of  the  Bay  and 
considerable  dredging  would  have  to  be  done  to  get  boats  with 
any  draught  to  it  on  the  Bay  Side.  Deep  water  27  or  28  feet  on 
the  Sound  Side  iB  oloser  and  could  be  reached  with  a  dock.  large 
boats  come  in  very  close  on  the  Sound  Side  and  the  Greenwich  Ferry 
comes  in  right  at  the  end  of  it.  He  could  give  me  no  approximate 
price  on  this  property  and  said  that  the  owners  were  simply 
impossible.  If  any  commandeering  is  to  be  done  I  should  judge 
that  these  are  the  people  who  deserve  to  get  it.  He  thought  they 
might  agree  to  a  ground  rent  proposition,  but  they  never  sold  if 
they  could  help  it.  I  might  also  mention  that  they  also  own 
most  of  the  property  along  Eaton's  Heck  where  we  saw  them  taking 
out  sand  for  Hew  York,  up  beyond  Horthport. 

Third:  Hext  to  the  Jones  property  oh  the  left  as  you 
drive  in  from  the  main  road  there  is  what  they  call  "The  Pines"  - 
about  3  acres  all  told,  fronting  on  the  Sound  same  as  the  Jones 
property  and  bordering  on  the  main  road.  There  are  5  lots  with 
two  buildings  (honses)  next  to  this  he  thought  could  be  had  for 
^5000  and  about  10  lotE  with  three  houses  at  approximately  §20,000 
The  lots  are  60  by  100  ft.  and  are  adjoining  to  the  3-fl^p  acres 
above  mentioned.  He  thought  this  3  acre  (The  Pines)  could  be 
had  for  $11,000  or  perhaps  less  -  and  perhaps  the  whole  plot  3-^Jk 
acres  and  15  lots  could  be  had  for  about  $36,000. 


Fourth:  The  Brown  property  at  Bayville  (see  Map):  This  con¬ 

sists  of  two  riots  one  of  90  acres  and  one  of  30  acres  both  facing  on 
the  northwest5 arm  of  the  Bay  and  shut  in  by  adrawbridge.The90 
acres  has  a  fine  house  on  it.  In  front  is  flat  and  level  and 
runs  gradually  back  to  high  ground  at  the  back  to  the  main  road. 

The  thirty  acies  faces  the  H.  W.  arm  of  the  Bay  and  runs  back  to 
the  road/  Of  course,  considerable  digging  out  would  have  to  be 
done  to  get  boats  of  any  size  into  the  arm  of  the  Bay,  and  the le 
is  the  drawbridge  (opening  48  feet  on  each  side )  to  contend  with. 

This  bridge  is  just  three  miles  from  the  Oyster  Bay  depot.  I 
+vinnah+  that  nerhans  "The  Pines"  property  and  either 

one  or  both  the  Brown  properties, taken  together, might  give  sufficient 
-Pm-  +Vm  needs  While  they  are  not  adjoining  they  are  close 
together  and  connected  by  the  main  road.  The  Pines  property  would 
give  the  Sound  water  front  and  the  Brown  property  give  the  necessary 
foom  for  th^ housing  part  of  the  proposition.  There  are  very 

few,  if  any,  houses  to  be  had  in  Oyster  Bay  proper,  and  wi 
trolley  lines,  the  housing  proposi tion  would  have  to  ^takenoare 
of  as  a  cart  of  the  general  scheme.  There  is  other  land  beyond 
the  Irown  place  that  could  be  bought  if  more  land  ^  desired,  f- 
^mith  said  he  thought  the  Brown  property  would  cost  from  #2 000  to 
$2500  per  acre-  bufif  Ur.  Brow/could  sell  all  his  holdings  there 
he  might  take  less.  Said  Brown  had  been  disappointed  in  the 
sunnort  given  him  to  build  up  a  fine  residential  property  and  had 
remarked  that  he  "wished  he  had  never  seen  it"  and  thought  Brown 
would  be  glad  to  get  out  for  what  it  had  cost  him.  Could  not 
say  how  much  that  was.  Of  course  this  Bro^property.ThePines^ 
and  the  Jones  property  are  all  over  three  miles  from  the  Railroad. 
Oyster  Bav  being  the  Ry.  Station.  The  roads, of  course,  are 
fine.  We  drove  over  them.  Ur.  Smith  says  the  ice  conditions 
in  the  Bay  were  very  unusual  last  Winter  and  that  usually  naviga¬ 
tion  is  only  interrupted  for  30  to  45  day®.  in  has 

Channel  has  never  been  known  to  shift.  The  tide  in  the  ^a8 
a  rise  of  7  feet.  Average  rents  in  Oyster  Bay  where  there  a£e 
any  for  rent,  5  or  6  rooms  with  modern  improvements,  Heat  and  Bi ath, 
!s  aboSt  20  to  $25.  Top  notch  8  or  9  rooms,  y40  to  45  dollars. 
Anything  higher  there  is  little  or  no  use  trying  to  rent. 
are,  however,  very  few  vacant  houses  of  any  kind  to  rent.  iB 

fine  and  general  health  excellent.  Market  for  provisions  are

tance  south  of  Glen  Head  Station.  -  40  acres  on  the  corner  suitable 

for  housing  or  laboratory  purposes,  and  15  acres  on  the  Shore 
of  Hempstead  Harbor,  with  about  300  feet  of  water  front.  An  old 
dock  and  a  good  channel.  (tf.  s*  chart  wsfe  shows  13  to  18  feet 
depth,  This  property  can  be  bought  for  #2000  per  acre  on  the 
water  and  about  $1500  on  the  road.  Stern,  the  Dry  Goods  man  of 
Hew  York,  has  the  property  in  between.  The  property  is  known 
as  the  Estate  of  George  W.  Townsend.  There  is  a  large  power 
house  on  the  adjoing  property  Hassau  Electrio  light  Co.  Supplies 
light  to  muoh  of  long  Island.  Across  the  Harbor  are  the  sand  beds 
the  largest  on  the  sound,  they  say.  Boats  (tugs  and  scows)  go 
in  and  out  for  Hew  York  -  18  to  20  miles  away.  These  properties 
are  not  connected  except  by  roadway,  but  might  serve  the  purpose 
if  properly  arranged.  Would  have  water  front  nearer  Hew  York 
and  a  lot  of  30  acres  along  side  the  railroad  and  just  across  the 
main  drive  a  lot  of  30  acres  more  and  40  on  the  corner,  making 
with  the  water  fron  115  acres.  The  upland  100  acres  is  beauti¬ 
fully  located . Mr .  Smith  has  another  piece  of  property  right 
in  the  limits  of  The  City  of  Hew  York.  If  the  proposition  is 
not  too  expensive,  it  would  be  a  great  location  from  what  I  have 
heard  of  it,  Of  course,  I  have  not  seen  it.  It  is  known  as 
The  Zeraga  Estate  on  "Old  i’erry  Point"  It  has  114  acres,  86 
upland,  28  meadowland.  Has  one  and  one  half  miles  of  water  front, 
one  third  of  a  mile  being  on  the  East  Hiver,  minimum  depth  at 
bulkhead  30  feet.  The  Sound  Steamers  pass  here  very  close.  It 
is  said  to  look  almost  like  a  stone's  throw  from  the  land.  It 
is  four,  miles  from  a  Railway  station  on  the  Harlem  Railroad.  One 
and  one-half  miles  from  the  177th  St.  Trolley  Station  and  line 
to  Hew  York.  It  is  South  of  West  Chester,  bounded  on  the  West 
by  Westchester  Creek.  The  U.  S.  Chart  shows  well  in  shore  47  feet 
of  water  and  mid  channel  95  feet  right  opposite  the  Point,  The 
property  is  held  at  $660,000.  Probably  $500,000  would  buy  it. 

It  Beems  rather  remarkable  that  such  a  piece  of  property  so  close 
to  Hew  York  has  not  been  taken  up  before  this.  It  might  be  worth 
while  for  Mr.  Edison  to  drive  out  there  and  look  it  over.  Being 
bo  close  to  II ew  ^ork  it  would  to  Bomo  extent  eliminate  the  housing 
part  of  the  scheme.  Unless  there  is  some  drawback,  I  Jo  not 
know  about,  this  looks  good  to  me  if  the  price  is  not  prohibitive. 

!  Mr.  Smith  again  and  went  over  each  proposition  and 
finished  today.  The  water  at  the  Lighthouse  is  about  1/4  of  a 
mile  wide,  channel  about  300  feet.  There  was  no  mention  of 
any  price  for  the  properties  below  $1500  per  acre  and  from  that  to 
$4000  per  acre  according  to  location.  Center  Island  from  #4000 
up  for  residential  purposes  only.  Mr.  Smith  will  come  to  Hew 
York  at  any  time  to  look  at  The  Zeraga  place,  but  presume  Mr. 
Edison  would  prefer  to  go  over  it  alone  at  first.  Of  course, 

I  have  mentioned  no  names  to  anyone  here. 

With  best  wishes,  I  am, 

Sincerely  yours,

liy  dear  Hr-  Daniels: 

For  the  Inst  ten  days  I  huvo 
beon  hunting  for  proporty  near  iiev;  York  City,  ouitablo 
for  a  Laboratory. 

I  have  found  three  pluses  which  aro  vory 
favorably  eitua tod, with  vory  doop  water  near  shore. 

„nv  ono  of  thorn,  even  if  not  used  for  Laboratory, 
would  nuke  a  cheap  unnox  to  tho  Brooklyn  Ilavy  Yard, 
being  only  an  hour  from  the  Yard  by  wator.  Thoy  are 
on  tho  Sound. 

X  find  that  tho  further  you  go  away  from 
tho  suburbs  of  Hew  York  City,  the  more  costly  is  tho 
property  as  rich  mon  aro  buying  it  up  for  ostutos 
and  they  do  not  wont  to  be  close  to  the  City. 

Any  time  you  aro  roady,  I  will  take  you  in 
an  automobilo,  or  v.o  can  go  on  a  Kovy  boat,  and  you 
can  inspect  them.  I  think  now  is  the  boot  time  to 
got  proporty  choap  as  banks  are  not  loaning  money  for 
spoculativo  building,  and  proporty  is  not  so  much

Dear  Sir:_ 

Replying  to  yours  of  May  24th,  would  say,  we  manufacture 
the  common  charcoal,  sulphur  and  nitrate  of  Soda  black  powder, 
and  would  be  pl9ased  to  make  the  experiment  you  mention  X*  1 r 
any  advantage  to  the  government.  But  we  doubt  if  our  equipment 
would  be  as  satisfactory  as  some  of  the  other  mills.  We  are 
equipped  only  for  making  the  hand  grained  powder,  which  proves 
very  satisfactory  for  some  work,  but  for  other  work  is  not  as 
satisfactory  aB  the  corning  mill  and'prossed  powder. 

Our  process  is  to  pulverize  the  charcoal  and  sulphur 
and  then  to  mix  and  incorporate  the  sulphur,  charcoal  and  soda 
under  7  ton  chacer  wheels.  We  then  grain  it  through  sieves  and 
dry  it  at  a  temperature  of  about  200  degree  .Fahrenheit .  It  is 
then  run  into  glaze  barrells  and  polished,  either  with  or  without 
graphite.  Eliminating  the  preening  process  does  not  give  quito 
as  hard  a  grain  as  when  a  hydraulic  press  is  used. 

If  our  process  is  satisfactory,  we  will  ho  pleased 

to  hear  from  you.  ' 

Respectfully ,

Dear  Mr  Edison: 







Wo  ar/  in  receipt  of  your  wire  of  Hay  27th  which  reads 

"If  special  machine  is  all  ready  with  extra 
wheels  and  chain  block  please  put  it  in  con¬ 
dition  to  be  driven  to  Orange  in  regular  way 
with  tractor  wheels  removed  My  man  will  go 
down  and  get  it  Answer" 

In  this  connection,  would  state  that  your  man  arrived 
here  yesterday  to  drive  experimental  machine  over  the  rodds  to  your 
West  orange  Laboratory,  but  am  sorry  to  report  that  the  machine  on 
which  the  experiment  was  made  was  sold  by  us  and  the  wheolB  and  drums 
put  in  storage  here. 

During  the  winter  time  we  equipped  the  machine  with  special 
body  and  the  experimental  wheels  and  took  Bame  over  into  Virginia  for 
a  test.  We  drove  into  a  very  muddy  lane,  which  separated  two  plowed 
fields  and  after  going  in  about  100  yards,  the  mud  got  worse  and  the 
machine  stalled.  The  mud  filled  in  the  space  between  the  cleats  on  the 
roar  drums  and  gave  us  almost  a  smooth  surface,  consequently  no  traction 
and  the  wheels  simply  spun  around.  The  front  wheels,  on  account  of  the 
width  of  the  drums  pushed  up  the  mud  in  euch  a  manner  aB  to  prevent  ua 
from  moving. 

In  our  opinion,  your  idea  should  be  rigged  up  to  one  of  our 
ton  truoks  rather  than  our  standard  model  "T"  car,  as  the  low  gear  ratio 
contained  in  the  ton  truck  will  give  you  the  desired  power.  We  also  be¬ 
lieve  that  the  oleats  on  the  drums  should  be  about  an  inch  wider .  It 
would  also  be  our  recommendation  that  the  drums  on  the  front  wheels  be 
reduoed  to  about  one-half  their  present  width,  which  would  enable  them  to 

cut  through  the  mud  to  some  extent  rather  than  hold  you  back,  which 
they  do  in  their  preeent  shape  ,  We  had  intended  to  proceed  with  your 
experimental  work  as  outlined  before  you  went  away,  but  Mr.  Ford 

turned  over  our  Building  to  the  Government  and  we  were  consequently 

forced  to  locate  in  small  temporary  quarters,  where  we  do  not  have  the 
facilities  or  the  help  to  carry  on  these  experiments. 

Your  Chauffeur  advised  that  he  talked  with  you  over  tele¬ 
phone  and  explained  the  situation  to  you  and  that  you  requested  that 
the  experimental  wheels  and  drums  be  shipped  to  you  by  Express  to  your 
Laboratory  at  West  Orange.  Please  bo  advised  that  this  equipment  is 
going  forward  today  and  would  suggest  that  as  you  are  located  near  our 
Long  Island  City  Assembly  Plant,  that  you  get  in  touch  with  them  and 
feel  sure  that  they  will  be  glad  to  co-operate  with  you  in  this  matter. 

Regretting  that  we  were  unable  to  proceed  with  the  experi¬ 
ment  at  this  Branch,  we  are,

Subject:  Extension  of  release  from  active  duty 

granted  to  George  3.  Hanford,  Jr., 

Oiler,  Naval  Coast  Defense  'deserve. 

Class  4,  USNRF.48  Spruce  Street, Bloomfield, II.  J. 

Dear  Sir: 

1.  This  man's  present  release  from  active  duty  expires 
July  5,1918. 

2.  This  man  has  become  one  of  an  active  party  of  three  men. 
who  are  valuable  to  me  in  the  development  of  an  important  experi¬ 
ment  which  is  now  at  a  critical  stege.  Our  tests  in  Florida 
were  very  successful  and  opened  a  large  field  for  future  efforts. 

Our  work  for  the  next  few  weeks  will  be  conducted  from  my-  laboratory 
in  Orange,  P.  J.  ,'le  will  then  locate  upon  a  n ew  proving  ground 
here  in  the  North. 

3.  •  In  order  to.  eliminate  the  necessity  of  securing  extensions 
of  his  release,  I  will  now  ask.  for  an  indefinite  release  from 
active  duty  for  this  man  Hanford,  such  release  to  remain  in  force 
until  thiB  important  Government  work  is  completed,  which  may  take 
from  three  to  five  months  and  possibly  longer.  .Of  course,  I  will 
notify  you  at  once  when  his  services  are  no  longer  valuable  to 
this  work;,  at  which  time  he  will  report  fo.r  assignment  in  the  . Navy. 

4.  "  It  is  important  to  confine  the  knowledge  of  the  workings 
of  this  oxperiment  to  .the  smallest  possible  number  of 'people. 
Therefore,  I  am  asking  for  the  continued  help  of  Hanford  until  the 
experiments  are  completed,  so  that  I  will  hot  have  to  take  in  a 
new  man.

Gentlemen: - 

At  the  meeting  of  the  Laboratory  Com¬ 
mittee  of  the  Naval  Consulting  Board  held  today, 
it  v/as  decided  that  the  enclosed  list  of  sugges¬ 
tions  for  development  and  investigation  was  not 
sufficiently  broad  and  comprehensive  to  inolude 
the  different  classes  of  work  which  would  pro¬ 
bably  be  brought  to  the  laboratory  and  it  was 
suggested  that  the  oommitteo  write  to  eaoh  member 
of  the  Board  asking  them  to  suggest  additions  and 
amendments  to  the  enclosed  list.

Report  to 

on  the  subject  of 
the  proposed 

- oOo - 

This  Report  was  made  by  the 
and  was  approved  by  the 

June  8,  1918 . 

From:  The  Naval  Consulting  Board, 

To:  The  Secretary  of  the  Navy. 

Tills  report  was  compiled  hy  experts  of  the  Board  who 
visited  and  interviewed  various  members,  officers  of  the  Navy 
and  others  and  who  personally  inspeoted  the  following: 

Bureau  of  Mines  laboratory;  Bureau  of  Standards  Labora¬ 
tory  and  Shops;  The  Remington  ArmB  Company  Plant;  The  Engineer¬ 
ing  Experiment  Station, Annapolis;  The  Electrical  Testing 
Laboratories,  Hew  Vork  City;  The  General  Electric  Company  Shops 
and  Laboratories,  Soheneotady,  H.Y.;  The  Shops  at  the  Torpedo 
Station,  Newport;  The  ShopB  at  the  Submarine  Base, Hew  London; 

The  Shops  at  Gould  and  Eberhardt,  Newark,  H.J. ;  Tho  Shops  at 
The  General  Vehicle  Company,  long  Island  City. 

While  this  investigation  is  not  yet  completed,  we 
respectfully  make  tho  following  reoommendations  at  this  time 
with  the  object  of  giving  a  basis  for  the  consideration  of  the 
mattor  by  the  Committee: 

It  should  be  borne  in  mind  that  these  reoommendations 
are  intended  to  cover  simply  an  initial  installation  which  will 
serve  as  a  nuoleus  around  whioh  to  center  future  developments 
and  it  is  anticipated  that  such  developments  will  have  to  be 
extensive  and  adequate  to  meet  problems  whioh  can  not  now  be 


Transportation  of  Freight  ana  Eassen) 

Shore  now  exist  facilities  for  transportation  by 
both  rail  and  water  to  the  U.  S.  Haval  Magazine  on  the  property 
adjoining  the  proposed  location  of  the  laboratory  at  Bollevue, 
Washington.  She  Baltimore  b  Ohio  Railroad  have  a  track  along 
the  eastern  boundary  of  the  property,  and  thiB  track  should  be 
extended  down  to  the  waterfront  for  the  transportation  of 
materials  including  coal  for  the  power  plant. 

As  the  river  is  shallow  along  the  front  of  the 
property,  it  will  be  necessary  to  extend  the  wharf  out  a  distance 
of  at  least  900  feet  in  order  to  secure  sufficient  dopth  of 
water  to  permit  the  docking  of  small  naval, vessels,  such  as 
torpedo  boats.  Facilities  for  both  rail  and  river  transporta¬ 
tion  should  be  provided  at  once,  so  that  the  materials  for  con¬ 
struction  of  the  plant  can  be  easily  delivered  at  the  property. 

With  reference  to  passenger  transportation,  it  would 
be  desirable  if  the  street  railway  line,  which  now  crosses  the 
B  &  0  track  a  short  distance  north  of  the  property,  should  ex¬ 
tend  its  line  down  to  the  laboratory  by  installing  a  trolley 
wire  over  the  railroad  track. 

Build in kb 

She  buildings  to  be  provided  should  cover  accommoda¬ 
tions  for  office,  drafting  room,  machine  shop,  chemical  and 
physical  laboratories,  rooms  in  which  inventors  and  scientists 
oan  develop  their  ideas  without  undue  publicity,  pattern  and 
woodworking  shop,  forge  shop;  and  possibly  furnaces  for  both 
brass  and  steel  castings.  The  power  house  should  be  located 
near  the  waterfront  in  order  that  fuel  may  be  delivered  either 

As  there  is  ample  spaoo  on  the  property  for  future 
expansion,  one-story  fire-proof  buildings  ooulfl  he  erected  and 
used  to  host  advantage. 

]?or  this  purpose  the  saw-tooth  type  of  building  is 
preferable  owing  to  the  efficient  and  satisfactory  lighting, 
and  a  print  of  a  preliminary  sketch  is  attached  hereto  showing 
a  building  of  this  type,  160  feet  wide  by  400  feet  long  with 
15  feet  olearanoe  between  floor  and  under  side  of  girders,  in 
four  bays,  eaoh  30  foot  in  width  and  25  feet  clearance  in  one 
bay  40  feet  in  width;  all  with  columns  spaced  20  foot  centers 
through  the  length  of  the  building.  The  drainage  from  the 
rood  would  be  carried  down  the  columns  on  the  inside  of  the 
building,  and  would  be  of  ample  capacity  to  take  off  any 
possible  accumulation  of  water. 

This  building  Bhould  be  located  near  the  river 
idiich  runs  from  north  to  south,  tho  length  running  baok  from 
the  bluff  which  at  this  point  is  approximately  16  feet  above 
mean  high  water.  The  saw-tooth  roof  construction  should  run 
from  east  to  west,  so  that  tho  glass  will  face  the  north,  thus 
giving  the  most  satisfactory  light  for  all  purposes  inside  the 
building.  By  making  tho  fotir  sides  of  the  building  largely  of 
glass,  there  should  be  no  dark  corners. 

The  most  satisfactory  material  for  roofing  is  Gypsum 
Tile.  This  material  being  fire-proof  and  non-oonduoting  and 
by  a  suitable  covering  on  the  outside,  waterproof. 

The  floor  would  be  of  concrete  slabB  4"  in  thickness 
with  a  2"  covering  of  cinder  concrete  tamped  between  stips  of 
wood  tfc  which  would  be  nailed  2"  spruce  or  hemlock  planking,  and 

that  portion  selected  for  offioo  ana  drafting  room  covered  by 
7/0 "  maplo  flooring.  Partitions  which  dould  be  easily  erected 
and  taken  down  at  small  expense  nhonia  be  maao  of  Pyrobar  slabs. 

The  onrtaln  wells  would  be  built  of  brick  unless  it 
should  be  doterminoa  that  concrete  could  be  Beoured  at  a  lower 
figure,  which  can  only  be  determined  at  the  time  that  actual 
bids  are  secured. 

The  approximate  cost  of  the  above  building  ready  for 
occupancy  including  the  necessary  radiators  for  heating  would 
be  §190,000,  and  there  are  companies  who  will  enter  into  a  con¬ 
tract  to  complete  the  structure  inside  of  60  days  from  signing 
the  agreement. 

power  House 

It  would  seem  advisable  to  install  for  immediate  use 
while  the  permanent  power  plant  is  being  erected,  a  temporary 
power  equipment,  and  the  Bureau  of  Steam  Engineering  at  Washing¬ 
ton  is  prepared  to  furnish  information  which  has  been  sent  to 
them  in  reference  to  second-hand  power  equipment  which  could  be 
borrowed  or  secured  at  onoe  at  a  low  figure. 

An  ample  supply  of  electric  current  for  power,  light¬ 
ing,  and  experimental  purposes  must  be  available,  and  at  this 
stage  of  the  enterprise  it  is  impossible  to  determine  the  max¬ 
imum  requirements  so  that  provision  should  be  made  for  future 

A  brick  powdr  house,  as  per  sketoh  attached,  60  ft. 
hy  100  ft.,  can  be  erected  at  a  cost  of  approximately  §35,000. 
The  approximate  cost  of  the  Power  Plant  would  he  about  §100,000, 


Battern  Shop.  Store  House,  gorge  Shop. 

It  is  proposed  to  erect  a  pattern  shop,  40  feet 
by  100  feet,  a  store  house,  60  feet  by  100  feet,  and  forge  shop 
40  feet  by  60  feet,  at  a  total  cost  of . 034,000. 


In  securing  quotations  of  the  equipment  for  power 
plant,  shop,  laboratory,  offices,  etc.,  no  attempt  was  made 
to  obtain  lowest  prioeB,  the  endeavor  being  rather  to  make 
liberal  allowance  for  all  contingencies,  and  thorefore  the 
figures  given  are  higher  than  would  be  the  oasa  in  the  event 
of  competitive  prioeB  being  secured. 

An  endeavor  has  been  made  to  so  proportion  the 
standard  equipment  that  it  will  be  complete  and  enable  the 
building  and  testing  of  the  different  classes  of  apparatus 
which  in  the  opinion  of  the  Board,  should  be  developed  at 
the  laboratory,  it  only  being  necessary  to  add  the  special 
equipment  required  by  each  case  as  it  is  taken  up. 

Machine  Shop  Equipment. 

This  equipment  Bhouia  comprise  tools  of  the  very  test 
make,  complete  in  every  particular,  ana  covering  the  entire  range 
of  orainary  shop  praotioe.  All  tools  as  far  as  practicable  Bhouia 
have  inaiviaual  motor  arive,  bo  as  to  largely  obviate  the  use  of

Brass  and  Steel  Furnaces, 

There  is  a  great  demand  By  different  departments  of  the 
Government  for  small  steel  eastings  and  it  has  Been  suggested 
that  the  equipment  at  Bellevue  should  cover  an  eleotrio  steel 
fumaoe  of  at  least  one-ton  capacity.  A  Brass  furnace  iB  also 
recommended.  •

not  performed  any  work.  As  it  will  he  difficult  to  secure

he  needed,  it  might  ho  possible  to  appropriate  some  of  the

A  large  number  of  motors  and  Borne  of  the  tool

June  11th,  1918. 

Mr.  Thomas  A.  Eaison, 

Edison  laboratory, 

Orange,  Hew  Jersey. 

Dear  Mr.  Edison: 

The  week  following  my  visit  to  you,  and  our  talk  over  the 
question  of  listening  for  torpedoes,  I  brought  the  natter  up  be¬ 
fore  the  Ship  Protection  Committee  of  the  United  States  Shipping 
Board,  and  got  that  oommittee  to  reoommend  that  ships  traversing 
the  submarine  zone  should  have  internal  bow  tanks  fitted  with 
miorophones  placed  in  them  with  extension  wires  to  listening  post 
at  the  wheel. 

I  told  the  oommittee  of  the  work  which  you  were  doing,  and 
that  you  expected  that  you  wouia  be  able  to  get  a  more  advantage¬ 
ous  placing  of  the  miorophones,  but  that  you  felt  that  it  would  be 
worth  while  to  go  ahead  with  the  plansa  which  I  recommended,  and 
that: substitute  or  ohange  oould  be  made  later  when  your  work  was 

I  also  mentioned  to  the  oommittee  the  xo  rk  which  you  were  do¬ 
ing  with  the  sea  anohor  and  told  them  in  general  terms  the  results 
whloh  you  had  acoomplished,  and  stated  that  I  expected  to  keep  in 
touch  with  you  regarding  future  developments  in  this  line. 

I  would  very  much  appreciate  it  if  you  would  let  me  know  the 
progress  of  this  work,  and  would  very  munh  like  to  witness  some  of 
the  tests  with  the  sea  anohor  if  you  are  to  make  any  in  the  near 
future.  If  this  can  be  arranged,  will  you  please  advise  me  at  my 

1  ri°?Tive4  laat  week  a  c°Py  of  a  confidential  report  from  the 
offioe  of  -Naval  Intelligence,  based  on  information  obtained  from 
abroad.  This  report  stated  that  in  the  month  of  April,  this  year, 
a  series  of  tests  were  oonduotod  in  listening  to  torpedoes  fired 
in  the  vioinity  of  a  patrol  boat  equipped  with  what  is  known  as  the 
falser  apparatus,  which  I  understand  is  an  aeooustio  device,  and 
the  results  reported  were  that  the  torpedo  oould  be  detected  as 
soon  as  fired  at  a  distance  of  about  1200  meterB,  and  it  waB  recom¬ 
mended  that  additional  tests  be  made  to  follow  up  the  natter. 


Mr.  I.  A.  E. 
Sheet  #  2, 

June  11,  1918. 

The  report  from  the  Erenoh  ispurpsi  also  suggested  the 
possibility  of  the  use  of  a  sea  anohor  attached  to  the  bow 
of  the  vessel  by  means  of  a  hawser. 

Ijt  struck  me  as  rather  interesting  that  they  had  actu¬ 
ally  tumbled  on  to  the  thingB  with  whichyon  have  been  work¬ 
ing  for  such  a  long  time. 

thanking  you  in  advance  for  the  courtesy  of  your  reply.

and  Commander  Wilkinson  and  to  our  Department.  If  you  see  any 
objection  to  this  arrangement,  I  will  take  it  up  with,  one  of  the 
other  Bureaus  in  Washington  to  make  some  further  adjustment,  but 
changes  in  accounting  matters  there  involve  so  much  red  tape  that 
I  would  be  glad  to  avoid  the  undertaking. 

With  regard  to  the  time  that  these  matters  will  go 
on  I  should  say  it  was  absolutely  indefinite.  There  are  more 
officers  being  attached  to  the  staffs  Duil^up 

equipped  for  new  work  and  the  plant,  itself,  is  being  built  up 
around  the  results  there  produced,  which  have  been  most  encourag- 

I  remain. 

Very-sinoerely  your3,

liy  dear  Hr.  Edison: 

X  was  very  pleased  to  learn  from  Hr.  Schwab  that  you  at¬ 
tended  the  launching  at  Newark  Bay,  and  was  very  sorry  that  I 
was  not  there  to  welcome  you. 

I  hope  you  liked  the  story  I  told  in  my  recent  speech, 
a  copy  of  which  I  am  inclosing. 

Hoping  you  are  quite  well,  and  assuring  you  that  I  will 
always  consider  it  an  honor  to  see  you  when  you  are  in  Washing¬

Dear  Sir 

A  cablegram  of  Juno  11th  atuting  that 
information  ie  desired  by  tho  Italian  Government 
regarding  liaison  system  of  signalling  at  sea  invis¬ 
ibly  to  submarines  has  been  shown  to  mo.  In  reply, 
I  desire  that  the  following  shall  be  communicated 
to  Dr.  Vi.  I’.  Durund,  tho  Scientific  Attucho  of  tho 
Committee  in  Paris  for  transmission  to  the  Italian 

She  working  model  is  being  mude  for  me 
at  the  iioy  host  Ilaval  lard  by  two  mechanics  from  a 
submarine.  Shis  modol  should  have  arrived  at  Orunge 
befovo  this.  I  will  communicato  and  find  out  when 
it  will  probably  arrive. 

Cho  idea  is  to  uso  throe  aluminum  discs 
each  of  12  inchos  diameter,  with  one  millimotor  space 
between  theso  discs,  tho  surfaces  boing  coated  with 
dull  lumpblack.  A  small  spiral  filament  incandos-  . 
cent  lamp  at  tho  center  sends  out  two  parallel  bearaB 
of  light.  She  disks  aro  rotated  by  a  small  motor, 
making  6,000  revolutions  per  minute. 

Iho  lamp  is  placed  as  high  up  on  tho  mast 
as  possible  and  provided  with  a  wind  shield  made  of 
sheot  celluloid  hold  in  a  frurae.  V'ho  lamp  is  thus 
kept  parallel  notwithstanding  the  rolling  of  the  ship 

Jin  addition  hue  boon  made  of  a  cup  contain¬ 
ing  mercury  and  an  electric  contuot  so  that  in  case 
of  accident  tho  lamp  ie  cut  out  before  the  beam  of 
light  reachoB  eueh  an  ungle  that  it  can  be  oeon  by 
a  Bubmurino. 

Experiments  made  with  a  pipe  filled  with  vory 
small  tubes,  lanpblackoc  inBide,  with  a  filament  lump 
in  the  centor,  proved  that  on  the  darkeut  night  no 
light  was  viniblo  from  a  height  28  foot  abovo  tho  water 
when  the  tubes  were  80  feet,  but  thiB  only  took  care 
of  the  rolling  of  the  ship  and  did  not  provide  for 
pitehing.  It  io  only  by  tho  use  of  a  gyroacopo  that 
tho  light  may  be  Boon  in  ovory  direction  by  observers 
up,  say,  80  feet  abovo  the  water  line  and  not  by  an 
observer  28  foot  about  water  line  which  is  the  supposed 
limit  for  submarines. 

i’here  is  considerable  difficulty  in  getting 
the  lamps  to  function  properly,  but  X  think  the  Italians 
can  make  a  succeBB  of  it. 

As  soon  as  the  model  arrives,  I  shall  experi¬ 
ment  with  it  und  lot  thorn  know,  but  they  should  not 
wait  for  mo  ae  I  am  very  busy  on  other  things. 

lours  vory  truly.

pear  Sir:- 

Enolosed  please  find  confirmation  of  telegram  sent  you 


Our  Chamber  of  Commerce  believes  that  you  must  realize 
the  importance  of  Key  West.  If  properly  fortified  and  made 
a  First-Class  Naval  and  Sub-llarlne  Base,  its  looation  would  make 
it  the  Key  to  both  of  the  entrances  to  t&e  Gulf  of  Mexico.  If 
in  the  future,  Naval  battles  should  be  fought  for  oommand  of  the 
Gulf  waters,  this  is  the  strategic  point  from  whioh  the  ships  of 
our  Navy  would  reoeive  their  supplies  and  the  sole  harbor  that 
would  be  available. 

Having  brought  this  matter  to  your  attention,  we  feel 
that  you  will  do  all  in  your  power  for  a  favorable  consideration 
in  the  house  of'  the  Senate  Amendment,  which  we  believe  to  be  a 
matter  d>f  importance  to  the  entire  Nation.

My  dear  Mr.  Edison;- 

Replying  to  your  letter  of  the  14th 
instant,  per  Mr.  Hanford,  conoerning  the  work  of  the 
two  eleotrioians  Payne  and  Gerbode. 

Mr.  Morgan  reports  to  me  that  these  men 
have  been  working  whenever  their  other  duties  would  per¬ 
mit.  Recently  the  submarines  have  been  quite  active 
and,  therefore,  the  men  have  not  had  as  much  time  as 
they  originally  anticipated. 

I  enclose  herewith,  a  copy  of  a  report 
received  from  the  men  to-day,  vdiieh  outlines  the  pro¬ 
gress  they  have  made  so  far. 

I  have  again  directed  Mr.  Morgan  to  keep 
in  close  touch  with  this  work  and  to  inform  me  when  it 
approaches  completion. 

Trusting  that  this  is  satisfactory,  I  am 
with  great  respeot. 

Sincerely  yours, 

Thomas  A.  Edison,  Esq. , 

Orange,  H.J. 


From:  P.D. Payne,  A.G.Gerbode,  U.S.1J. 

To-  Commandant,  U.S. Naval  Station,  Key  West, Fla. 

Subject:  Report  on  experimental  work  for  Thomas  A.  Edison. 

1.  Amount  of  material  drawn  by  us  to  date:  12  lbs.  aluminum  ingot, 

11  lbs.  magnet  wire. 

Work  received  by  us  from  machine  shop(material  drawn  by  machinists) 
3  brass  gyro  wheels  from  rolled  stock  drilled  and  tapped  for  balancing 
screws,  1  brass  (oast)  gimbal  ring  with  4  tapped  stud  holes  1  °*st  iron 
gimbal  ring  with  2  bearing  steas  and  2  tapped  holes  for  studs,  2  iron 
gimbal  bars  fitted  with  clamping  screws  and  2  tapped  stud  holes,  1  cold 
rolled  steel  armature  shaft  with  core  and  commutator  fitted  and  trued, 
100  copper  washers,  1  counter  weight  from  rolled  brass  fitted  with  4 
screws,  5  aluminum  discs  with  grooves  out,  2  iron  strengthening  pieces 
fitted  to  supporting  frame,  2  iron  brackets  with  set  screws. 

2  Since  Mr/  Edison's  departure  we  have  done  the  following  work  on  the 
experiment :  After  trying  out  the  new  motor  with  gyrp  wheels  we  found 
that  the  5/16"  shaft  was  too  light, therefore,  we  installed  a  25/64 
shaft  which  necessitated  rebuilding  and  rewinding  of  armature,  also  the 
installation  of  a  new  pair  of  bearings  which  we  provided. 

Upon  completion  of  motor  we  proceeded  to  balance  wheels  statically  and 
dynamically.  We  then  mounted  the  gyro  element  in  the  gimbals  and  noted 
that  the  supporting  frame  was  too  springyand  decided  on  reinforoing 
same.  In  our  original  design  of  the  inner  gimbal  we  allowed  8  lbs 
for  the  weight  of  light  discs  but  after  the  discs  were  made  as  light 
as  practicable  they  were  far  in  excess  of  this  wdsight  making  it  ne- 
oessary  to  design  a  new  gimbal.  This  gimbal  is  not  completed  but  is 
now  being  made.  In  our  efforts  to  get  the  desired  pendulous  effect 
we  found  it  necessary  to  have  a  counter  weight  made  to  mount  an  the 
motor  as  we  did  not  have  clearance  enough  in  supporting  frame  to 
allow  of  lowering  motor  the  proper  distance.  The  glass  bulb  with 
oopper  contacts,  for  automatically  turning  out  the  light  in  case  of 
trouble  in  mechanism,  which  Mr.  Hayes  had  blown  for  us,  came  to  us 
broken  and  we  have  yet  to  construct  a  new  one,  the  material  for  which, 
we  have. 

3.  Owing  to  war  conditions  it  is  not  practicable  for  us  to  make  an 
estimate  on  the  length  of  time  required  to  finish  this  machine.  The 
greatest  delay  so  far  has  been  caps ed  by  our  trips  to  sea  and  as  we 
oannot  foresee  those  trips  it  is  impossible  to  say  even  approximately 
when  the  model  will  be  completed.  However,  we  will  say  that,  barring 
such  interruptions,  we  can  probably  turn  the  finished  machine  over  to 
Mr.  Edison  three  weeks  from  date.

is  the  one  who  would  superintendent  the  tost.  Chore 
will  be  somo  little  work  in  preparation  before  tho"  tost 
can  bo  made. 

Inasmuch  as  there  aro  usually  soveral  cargo 
boats  ot  anchor  in  the  iiarbor,  waiting  for  convoys,  Mr. 
liaison  thinks  that  possibly  you  might  bo  .able  to  got  an 
open  permission  to  take  ono  of  those  bouts  out  us  far 
as  tho  Ji’isliiiig  Hanks  for  tho  test,  after  which  sho  could 
roturn  to  hor  anchorage  in  tho  Harbor  and  wait  for  a

If  this  con  bo  done.,  it  would  be  tho  most  con¬

and- expect  to 'go  down  to  the  Aberdeen  Proving  Grounds

One  of  the  itoniB  in  our  program  will  be  the

in  the  neighborhood  of  Sandy  Hook  practically  all

superintend  the  test.  There  will  be  Borne  little 

Inasmuch  as  there  are  usually  several  cargo

Mr.  Edison  thinks  that  possibly  you  might  be  able 
to  get  an  open  permission  to  tske  one  of  these

I  entirely  disagree  with  the  report  of  a  majority 

of  the  Committee  in  almost  every  instance.  Their  idea  of 

the  character  of  the  Laboratory  is  quite  different  from  that 

which  I  have  always  considered. 

The  Government  already  has  a  Research  Laboratory 
iu  the  Bureau  of  Standards,  where  there  is  plenty  of  ground 
and  a  fine  working  force  capable  of  unlimited  extension. 

She  Government  also  has  a  Testing  Laboratory  at 

Annapolis,  whore  efficiency  constants  and  effectiveness  of 

/  / 

Haval  Machinery  can  be  and  already  are  tested.  There  are 
other  Research  Laboratories  connected  with  the  various  Bureaus. 

The  Government  has  no  Laboratory  arranged  on  special 


lines,  whereby  ideas,  suggestions  and  adaptations  of  tho 

latest  discoveries  or  inventions  can  be  carried  out,  con¬ 
structed  and  tested  with  groat  rapidity.  Such  a  Luboratar  y 

need  not  do  any  extensive  research  work  for  the  reason  that 

in  95'/j  of  the  cases  the  work  will  bo  done  under  known  facts, 

(of  which  there  is  an  almost  unlimited  number  ready  to  be 

used)  without  the  necessity  of  deep  scientific  research. 

i'his  laboratory  should  be  operated  on  a  War-time  basis  where 
extreme  rapidity  of  construction  of  the  various  appartus1 
and  devices  and  tho  testing  of  the  same  form  the  only  excuse 

for  its  construction. 

She  long  and  nocessary  delays  in  the  usual  Kesearch 

laboratories  should  bo  divorced  from  a  laboratory  of  this 

character.  Such  research  work  can  be  done  elsewhere,  (  1  ) 

at  the  Bureau  of  Standards  (2)  at  other  Government  Research 

laboratories,  and  (3)  through  spocial  business  arrangements 
with  many  of  the  large  Compnnioe  having  Hesearch  laboratories. 

Y.hile  Annapolis  might  be  a  good  place  for  a  Hocoarch 
Laboratory  of  the  usual  type,  it  would  be  totally  unfit  for  a 
practical  ihiporimenting  laboratory  constructed  and  operated  on 
the  lines  which  I  have  imagined.  Such  a  laboratory  as  last 
mentioned,  to  bo  successful,  should  be  as  near-  How  fori:  City 

as  possible,  (1)  in  order  that  materials  can  be  obtained  quickly 

(2)  where  the  business  heads  of  the  principal  industries  reside, 


and  ip)  from  whom  rapid  action  is  obtainable. 

only  site  near  enough  to  llew  York  City  (1)  where 


no  interference  is  possible ,  (2)  where  there  is  already  a. 
Proving-ground,  (3)  whore  unlimited  land,  is  obtainable, 

(4)  where  secrecy  is  easily  secured,  (5)  where  Hydro-Aero¬ 
planes  and  Submarines  can  bo  operated  and  tested  under 

actual  conditions,  is  the  site  covering  1300  acres  at  Sandy 
Hook,  already  owned  by  the  Government,  and  not  one-third 
of  which  is  nov;  being  utilized.  Sandy  Hook  is  £-l/2  hours 
distant  by  kailroad  and  one  hour  by  Motor  Boat.  Pv.'o  Street 
Car  linos,  1  Steamboat  line  and  1  Bailrodd  line  touch  one  end 
of  the  Hook,  and  there  is  a  large  number  of  villages  adjacent 

thereto .

What  v/e  wish  is  for  Ur.  Edison  to  ask  the  Secretary

the  last  eighteen  months  I  have  been  conducting  a  series  of 
experimentsSfor  our  Government  at  the  request  of  the  Secretary 
of  the  Havy. 

In  carrying  out  these  experiments  I  have  used  all 
the  resources  of  my  laboratory,  .including  the  two  machine 
shops  which  from  part  thereof.  This  experimental  work 
would  be  much  facilitated  if  I  could  obtain  without  delay 
some  additional  equipment  in  the  line  of  machinery,  but  i 
shopping  around  to  purchase  same  the  best  promise  of  deliv- 
ery  I  can  get  is  from  four  to  nine  months. 

The  blank  applications  for  priority  furnished 
by  your  Committee  do  not  provide  for  a  case  of  this  kind, 
as  they  are  intended  to  cover  caseB  where  the  applicant

it  is  of  an  experimental  nature  and  cannot  be  described  as

W©  delivered  powder  o  n  Saturday  by  auto.  We  made  inquiry 
from  the  Bureau  of  Explosives,  v/hloh  is  connected  with  the  Rail¬ 

road  company,  concerning  their  willingness  to  accept  these  goods 
for  shipment.  They  ashed  us  a  number  of  questions  which  we  an¬ 
swered,  but  up  to  date  have  no  t  received  their  reply,  but  pre¬ 
sume  that  they  will  accept  shipments  made  of  this  material, 

if  you  should  require  moro. 

As  this  lot  was  for  experimenting  we  put  it  up  in  two 
ways,  that  is,  polished  without  any  graphite,  and  the  balance  glazed. 
We  think  the  glazed  would  onus  e  a  trifly  more  smoke  and  somewhat 
protect  the  goods  from  raoiotur  e. 

If  thore  is  anything  further  that  wo  oan  do  in  this

July  19,  1918 

Mr.  Thomas  A.  Edison,  President, 

U.S.  Naval  Consulting  Board, 

Orange,  N.J. 

Dear  Mr.  Edison: 

Isn’t  it  a  good  Idea  for  the  Naval  Consulting  Board 
to  get  bhhind  the  fellows  working  at  New  ^ondon  and,  as  well  a_s 
possible,  help  develop  your  larger  plan  of  a  Navy  experimental 
department  there?  So  far  as  submarine  detection  work  has  gone, 
the  New  London  group  has  done  well.  They  have  shown  their 
willingness  to  do  radical  things.  I  understand  that  McDowell 
is  unpopular  in  some  bureaus  beoause  he  goes  so  far.  Isn’t 
that  a  good  sign? 

Taking  conditions  as  they  aotually  are,  not  as  we 
might  wish  them,  I  cannot  see  a  praotical  way  in  years  of  getting 
general  experimental  work  p»vperly  taken  care  of  in  our  Navy 
thru  the  entirely  untried,  unstarted  Washington  plan.  I  guess 
that  plan  is  really  on  the  shelf.  It  must  look  to  the  Secretary, 
after  hearing  his  many  divergent  advisers,as  tho  the  safest  step 
was  to  wait.  Troubled  with  all  sorts  of  material-priority  and 
,  labor-scarcity  difficulties,  1  should  hate  to  advise  a  start  dn 
a  new,  comprehensive  program  of  building  and  equipment,  but  the 
thing  could  grow.  Thl.  1.  really  being  iUuoW.bod  «t  No.  London. 

Mr.  Edison  -  2 

It  looks  so  simple  to  me  that  I  want  you  to  think  the  idea 
over.  If  you  favor  it,  I  think  most  of  the  Board  would  do 
so.  I  don't  like  our  being  stalled  so  long. 

If  you  do  not  want  to  bother  with  this  and  will  ex¬ 
press  your  ideas  to  Dr.  Hutchinson,  I  can  talk  with  him  about 

These  are  eome  of  the  points  in  favor  of  the  plan; 

1.  There  is  already  established  on  the  water-front 
a_t  New  London  a  fine  growing  nucleus  for  a  laboratory,  but  de¬ 
voted  now  to  only  a  part  of  Navy  needs. 

2.  It.  is  already  a  child  of  the  Navy,  in  which  the 
Navy  takes  interest,  but  it  is  based  on  civilian  work. 

3.  It  has  a  Navy  officer  in  command  who  is  young, 
active,  and  ambitious,  and  who  seems  to  appreciate  experimental 
work.  His  work  should  be  appreciated  and  greatly  broadened. 

He  can  cooperate  with  outsiders. 

4.  It  has  several  good  experiments  already  on  the 
staff,  such  as  Mason,  Bridgman,  Pierce,  and  Merritt.  Others, 
like  Pupin,  Whitehead,  Langmuirm  Chaffee,  and  Cady,  are  coOperat- 
ing  well. 

Mr  .Edison  -  3 

5.  It  already  has  quite  a  large  physioal  equipment, 

a  good  meohaniofs  shop  well  manned,  good  dock  or  wharf,  offioes, 
large  foundry  (practically  on  the  ground),  a  small  Bhip-way 
with  apparatus  for  drawing  out  and  launching  submarine  chasers, 
good  nearly  built  quarters  for  the  workmen,  a  concrete  exper¬ 
imental  tank  under  cover  (20  )  30),  etc.  Really  about  every¬ 
thing  is  there  which  we  planned  except  as  for  size,  and  there's 
plenty  of  spaoe  to  grow. 

6.  It  is  well  located  with  respect  to  salt  water. 

It  is  particularly  well  located  for  experiments  with  small  boats 
and  with  submarines  (the  submarine  base  is  only  a  short  distance 
up  the  river).  It  is  a  good  location  for  general  labor,  and  as 
most  of  the  labor  become  enlisted  Navy  men,  a  better  place  could 
soarcely  be  found.  Plenty  of  Navy  men  would  always  be  quickly 
available  at  this  place.  It  could  scarcely  be  excelled  from 
the  point  of  view  of  material  supplies  (your  strong  point) .  No 

part  of  America  is  so  well  fixed  for  formed  brass,  copper,  and 
iron.  No  where  else  is  it  so  easy  to  send  a  messenger  to  the 
factory  for  necessary  work  or  material.  Midway  between  Boston 
and  New  York,  it  also  lies  still  nearer  the  advantages  of  Prov¬ 
idence,  Bridgeport,  and  the  Naugatuok  valley.  Being  behind 
Long  Island  it  is  as  safe  from  attack  as  any  practical  shore 
station  could  be.  There  is  plenty  of  adjacent  land  for  growth 
and  land  whioh  is  not  valuable  for  other  purposes. 

Mr.  Edison  -  4 

I  have  not  been  in  olose  touoh  with  Mr.  Brunton  or 
Mr.  Condict  lately,  and  they  may  have  much  better  plans  than 
the  above,  but  it  is  more  important  that  we  start  helping  some¬ 
thing  which  oan  grow,  than  to  wait  for  a  perfect  and  mature 
plan.  It  is  impossible  to  produce  a  complete  Navy  laboratory 
at  once,  and  exceedingly  difficult  to  find  men  who  combine  the 
factors  of  Navy  connections,  interest  in  the  work,  youth,  and 
energy,  but  I  have  also  always  held  that  the  thing  was  very  de¬ 
sirable  (more  so  than  most  men  realize),  and  that  ib  could  grow 
by  a  natural  process,  if  deoently  encouraged.  I  think  the 
start  has  been  made,  that  it  will  continue  to  be  well  advanced 
under  the  present  plan,  and  that  we  might  be  of  great  help  by 
putting  our  shoulders  to  the  already  moving  wheel. 

I  think  we  could  carry  all  the  desirable  load  of  re¬ 
sponsibility  for  failure  of  experiments,  thus  relieving  the 
Navy  men,  and  thus  incorporating  a  faotor  whose  value  has  been 
pointed  out. 

I  can't  help  thinking  that  valuable  time  is  passing 
and  that  we  may  be  delaying  a  general  Navy  laboratory  by  not 
realizing  and  utilizing  the  conditions  at  New  London. 

Yours  very  truly.

Hy  dear  Hr.  Keadowcroft: 

In  accordance  with  your  conversation  with  me  this 

morning,  I  am  sending  hy  special  messenger  with  this  letter, 

two  samples  -  one  of  hakelite  carbon  and  the  other  of  standard 

carbon.  We  do  not  know  what  use  you  desire  to  make  of  these 

samples,  so  cannot  state  whether  they  are  likely  to  give  very 

satisfactory  results.  I  might  point  out  in  this  connection 


that  the  relative  performance  of  carbon  differs  with  the_/struc- 
ture  employed,  the  electric  circuit,  the  choice  of  voltages, 
current  densities,  etc.  Further,  we  find  that  various  varieties 
of  carbon  differ  greatly  with  respect  to  life  under  conditions 
of  use.  I  Bhould  be  glad  to  hear  from  you  whether  you  find  these 
samples  useful  or  not. 

Yours  truly,

We  understand  that  you  will  plaoe  an  order  covering  these  transmitters.

has  alroady  seen  the  Commanding  Officor  at  Fort  Hancock, 
arid  made  explanations  as  to  the  apparatus  and  the 
dosired  location,  all  of  which  was  apparently  satis¬ 

3.  It  woule  bo  nocessary  to  have  a  Survoyor  run 
baso  line's  on  . tho.  Hook  at  a  short  distance  away  from 
tho  main  land.  If  pormissiblo,  this  might  bo  done 
by  sonoone  from  the  iiew  York  offico  of  the  U.  S.'  Coast 
and  Goodotic  Survoy. 

4.  I,  therefore ,' bog  to  ask  that  the  Bureau  will 
extond  permission  to  mo  to  send  my  'Assistant  and  helpers 
(probably  not  mo. c  than  throe)  to  go  to  the  Sandy  Hook,

also  to  mako  use  of  the -Cower  as  an  observing  point,

I  have  received  your  favor  of  the  24th

vox-''  well  of  your  suggestion  to  Bond  a  pound  sample 
of  the  spoeial  nowdox'  xo  the  Chomical  Laboratory,  of  Explosives,  -South,  Amboy,-  U.J. 

I  will  attend,  to  -the  sending  'of  the  samplo 
as  soon  as  I  hoar  from  you  in  reply  to  this  letter. 

X  do  not  foci  quite  sure- vhothor  the  Chemical  Laborato r; 
you  refer  to  is  connected  with  one  of  the  xlailroud 
Companies,  or  vhothor  it  is  a  Govoinmont  Laboratory. 

I  will  await  your  advice. 

Hr.  Edison  it  glad  that  you  did  not  ciT0 
the  formula,  as  he  thinks  it  is  Just  as  well  that-  this 
should  bo  kopt  quiet  for  the  present.

Dear  Sir: 

Replying  to  yourB  of  July  36th,  would  aay,  the  Bureau 
for  the  safe  transpertaion  of  explosives  and  other  dangerous 
articles,  ia  a  bureau  established  by  practically  all  the  rail¬ 
road  companies  in  the  United  States,  and  the  Interstate  Commerce 
Commission  usually  follows  their  suggestions  in  making  regu¬ 
lation  for  transporting  explosives. 

Y/e  judge  that  the  chemical  Laboratory,  Bureau  of 
Explosives,  at  South  Amboy,  H..T.  belongs  to  this  same  bureau, 
and  we  do  not  think  that  it  is  a  government  laboratory. 

The  regulations  for  express  shipments  states  that 
samples  of  explosives  for  laboratory  examination  are  not 
to  exceed  a  net  weight  of  half  pound  for  each  sample.  This 
sample  is  to  be  placed  in  well  secured  metal  cans  or  glass 
bottles,  but  more  than  one  can  or  bottle  can  be  placed  in  a 
wooden  box. 

Y/e  are  enclosing  the  last  letter  from  this  Bureau 
of  Explosives  which  will  probbbly  explain  the  whole  matter.

Hr.  Thomas  A.  Edison, 

H.  J. 

In  response  to  your  request  of 
July  24th,  we  are  today  mailing  you,  under  separate 
cover,  by  Parcel  Post,  special  delivery,  a  sample 
sheet  of  what  we  know  as  our  Ho. 5  Sponge  Rubber. 

This  sheet  is  about  3/4  of  an  inch  thick.  We  have 
also  included  a  sample  of  our  Ho. 45  Red  Sponge  Rubber, 
which  as  you  will  note,  is  an  entirely  different 
produot.  He  can  manufacture  different  types  in 
between  these  two. 

For  your  information,  we  have 
conducted  considerable  experimental  work  for  the  Gov¬ 
ernment  in  the  development  of  this  material,  and  have 
at  the  same  time,  aoquired  considerable  information  as 
to  its  adaptability  for  various  purposes. 

Ve  would  be  very  glad  indeed  to 
give  you  any  information  in  our  power  as  to  this  mate¬ 
rial  if  we  had  the  neoessary  data  to  go  on,  as  for  the 
purpose  for  which  it  is  to  be  used..  Any  of  thiB  mate¬ 
rial  can  be  made  in  sheets  20  x  20,  and  of  practically 
any  thickness  required  up  to  2-l/2  inches.  Owing  to 
its  method  of  manufacture,  there  must  always  be  an  allow¬ 
ance  of  variance  of  1/8"  under  or  over  in  th*^ thickness . 
Till,  of  course,  can  be  30  x  30,  or  any  modification  of 
this  size  into  which  these  sheets  oan  be  out.  Should  it 
be  necessary  to  have  sheets  longer  than  SO  inohes^the 
material  oan  be  readily  a dived  and  cemented  and  made  into 
continuous  lengths  of  any  site  desired. 

If  this  material  is  of  sufficient  im¬ 
portance,  and  you  so  desire,  we  would  be  very  glad  to  have 
one  ofvour  men  come  to  the  factory  and  go  into  the  matter 
more  fully,  or  the  writer  or  one  of  our  factory  men,  when

periments  to  a  successful  conclusion.

My  dear  Mr.  Edison: 

We  are  trying  to  find  some  preparation  which  may 
be  applied  to  canvas  so  that  a  large  bag  may  be  made  to 
carry  fuel  oil.  The  bag  will  have  to  hold  from  two  to 
three  thousand  gallons  for  four  or  five  days  at  a  time 
and  a  slight  leakage  is  unimportant.  If  you  know  of 
anv  composition  that  would  accomplish  this  purpose,  I 
would  be  very  grateful  if  you  would  give  me  some  informa¬ 
tion  tabout  it.  The  bags  would  be  kept  filled  for  four 
or  fiveAdays,  then  emptied  and  rolled  up  for  ten  days 
or  two  weeks,  then  refilled  and  so  on.  Rubber  solutions 
would  be  attacked  by  the  oil  and  shellac  would  lack  the 
flexibility  required. 

I  am  well  and  happy  in  being  rushed  with  work  and 
hope  you  are  the  same. 

With  regards  and  best  wishes,

that  the  cloth- could  bo  coated  with  Viscose  which  is

of  tarpaulin  cloth,  linsocd  oil  cloth, • X  -moan  the  same 
as  coats  are  made.  Then  hang  the  bag  up  and  fill  with 
oil.  The  film  of  linseed  oil  is  not  soluable  in  oil  and 
some  films  are  not  even- softened  or  swelled  by  oil. 

Viscose,  I  understand,  is  made  by  the  American

My  dear  Mr.  Edison: 

I  have  your  telegram  regarding  Payne  and 
the  gyroscopic  lamp  and  have  telegraphed  you  today  that  the 
box  is  beinp-  shipped  but  that  Payne  cannot  be  granted  leave. 
It  appears  f hat  he, as  well  as  his  partner,  Sorb ode,  are  under 
charges  which  are  being  investigated  by  the  Navy  Department, 
anduntil  these  are  acted  upon  Admiral  Fletcher  cannot  grant 

I  appreciate  tlie  fact  that  the  completion 
of  this  apparatus  has  been  greatly  delayed.  I  have  made  fre- 
ouent  inquiries,  from  time  to  time,  regarding  progress  on  the 
work  and  was  several  times  informed  by  either  Payne  or  Gerbodo 
or  by  Gunner  Morgan,  whom  I  detailed  to  keep  an  eye  on  the  work, 
that  the  activity  and  frequent  short  cruises  of  the  vessel  to 
which  the  two  men  are  attached  interfered  largely  with  their 

On  Saturday  however,  in  company  with  Lieuten- 
ant  Quinlan,  I  witnessed  a  demonstration  of  the  lamp.  Lieutenant 
Quinlan  then  told  me  that  Payne  was  to  be  granted  leave, and  that 
he  would  go  to  Orange  and  demonstrate  the  apparatus  to  you.  Payne 
aupeared  very  anxious  to  make  this  trip  and  wanted  to  ship  the 
box  addressed  to  himself  at  Orange,  but  I  saidV  no,  tnat  the  Sup¬ 
ply  Officer  would  attend  to  shipping  it  and  that  it  should  be  ad¬ 
dressed  to  you. 

Today  I  received  your  telegram  and,  upon  malting 
investigations,  learned  the  reason  for  Payne  not  being  granted 
leave.  I  also  found  that  when  he  heard  he  could  not  have  leave 
Payne  went  to  the  express  office,  having  first  obtained  a  copy  ol 
the  Bill  of  Lading,  and  got  the  box,  which  had  been  sent  there 
yesterday,  and  took  it  some  place  out  in  town,  ’.men  questioned 
about  this  procedure  he  gave  no  very  definite  reply  otner  than 
that  he  stated  he  felt  he  had  an  interest  in  the  apparatus  and 
did  not  want  to  ship  it  and  have  any  one  else  open  the  box.  he 
also  spoke  of  "compensation"  and  vaguely  referred  to  some  agree¬ 
ment  that  he  had  made  with  you.  I  told  him  tnat  he  need  have  no 
cause  for  alarm,  but  that  he  and  his  companion  would  receive  full 
credit  for  their  work  and  for  such. ideas  as  may  have  been  pub  into 
the  apparatus  by  them. 

I  am  sorry  that  Payne  cannot  go  to  Orange  at 
the  ore sent  time,  as  it  would  undoubtedly  be  more  satisfactory  to 
you  to  have  him  demonstrate  and  operate  the  apparatus.  I  told  him^ 
however,  to  write  out  and  send  you  such  description  or  such  instruc¬ 
tions  regarding  the  apparatus  as  he  might  think  necessary.

Io  :  Thomas  A.  Edison. 

Subjeot:  Gyro  running  light  stabilizer. 

1.  The  experimental  machine!  which  we  have  huilt 
for  you  was  shipped  yesterday  by  express  by the  commandant 
of  the  Maval  Station.  In  our  plans  we  had  intended  for 
one  man  to  accompany  this  machine  in  order  to  demonstrate  to 
you  and  to  explain  it  but  as  he  was  not  allowed  to  go  we 
hereby  explain  to  you  improvements  necessary  as  we  have 
found  them. 

E.  First  a  motor  of  better  construction  is  necessary, 
this  motor  must  have  a  shaft  of  ample  size  to  oarrytheGyro 
whaelB  without  danger  of  them  becoming  out  of  allignment.tne 

ar Arsssa  s.'zss?  &&&£&&» 

leaves  the  horizontal  will  not  function  properly  if  the  machine 
has  exoessive  vibration. 

3.  This  olinometer  consists  simply  of  a  hemispherical 

....  a  marmirv.  There  is  anelectrical  connection 

impermanent  contact  with  the  mercury  and  another  eiectrioal 
o onneot ionplade  d  in  such  a  manner  that  the  mercury  will  touch 
it  when  the  container  is  tilted  more  than  twenty  minxes, 
this  closes  circuit  for  a  relay  which  upon  being' 
onens  the  light  circuit.  This  olinometer  may  be  mounted  on 
^partofthe  Machine  carried  by  the  inner  gimbal  ring. 

4.  The  leading  wires  for  the  mot or, light  and  olinometer 
should  be  installed  in  a  way  to  cause  less 

be  easily  accomplished  by  uBing  rubbing  contacts  at  all  |im- 
bal  intersection  s.  | 

6.  The  Gyro  elements  should  be  slightly  more  pendllous 
buttthe  upper  wheel  must  be  kept  above  the  axis  of  its  gimbal. 


6  Wa  have  found  that  a  refleoted/is  preferable  to

diameter  of  the  disks. 

7  She  whole  machine  must  be  protected  from  the  wind 
as  a  breeze  would  tend  to  energize  the  Gyroscope  and  throw 
it  off  its  plane.  This  protection  can  be  made  of  metal  or 
wood  with  windows  for  the  light.

to  the  secretary  of  the  Navy,  rnul  D,  i-cyne,C  ,E  .  ( General !  , 
attached  to  U.S.S.  K-3  was  sent  to  Orange  on  detached 
duty,  to  complete  an  experiment  upon  which  he  was  working 
with  me  when  I  was  at  Key  West  a  few  months  ago  . 

2.  Kis  transportation  and  subsistence  to  I!ew  York 
and  return  were. furnished,  but  he  was  not  furnished  with 
subsistence  while  on  detached  duty. 

3.  Payne  haB  stated  to  me  that  he  is  without  money 
to  pay  his  board  and  usual  expenses  while  here,  and  states 
that  he  has  written  to  his  Commanding  Officer  to  forward 
ehek  for  present. subsistence ,  but  states  that  it  has  not 

yet  been  received  by  him.  I  have  advanced  Payne  a  moderate 
amount  of  money  to  help  him  out,  on  the  understanding  that 
it  was  an  advance  against  the  money  for  subsistence  which 
he  says  he  expects  to  reoeive  through  his  Commanding  Offioer. 

4.  When  the  check  is  sent  to  him,  I  would  suggest 
that  be  aidressed  to  him  ca  e.  of  the  Edison  laboratory,

^itention  of  Hr »  i'/ia.  K .  Lleqdowcroft. 

Bear  Sir:  ~"  '■•■  V. 

In  accordance  with  your  request,  I  have  examined,  carefully 
the  schemes  for  detecting  submarines  as  suggested  by  Hr.  J.  n.  Ross. 
2he  underlying  principle  of  all  of  these  suggestions  is  the  prop¬ 
agation  thru  space  of  an  electro-magnetic  field.  She  weakness  of 
any  device  based  on  this  principle  is  that  tho  strength  of  such 
an  electro-magnetic  field  decreases  very,  very  greatly  with  dis¬ 
tance  from  tho  source  of  the  field.  Furthermore,  slight  changes 
in  a  magnetic  field  at  u  distance  from  its  source  will  not  be  de¬ 
tected  by  any  exploring  coil  placed  close  to  that  source. 

All  three  of  these  suggestions  are  exactly  the  same  inso¬ 
far  ns  their  electrical  principles  are  concerned  as  the  work  which 
Mr.  Stein  and  myself  carried  out  at  the  time  v/o  were  in  Orange, 
i'hese  proposed  methodB,  except  the  first  one,  are  novel  to  me  in 
tho  mechanical  means  employed.  However,  t.s  ubovo  stated,  the  basic 
principle  has  been  found  to  be  barren  of  results  for  the  purpose  de¬ 

I  am  returning  the  papers  herewith.

Dear  Sir :- 

neforring  further  to  your  letter  of 
August  11th,  end  its  enclosures,  I  submitted  the 
matter  to  two  experts  who  have  done  a  great  deal 
of  work  on  the  detection  of  a  submarine  by  elec¬ 
tro-magnetic  means.  These  experts  spent  a  very' 
considerable  tine  with  me  in  exploring  this  fiold 
very  .thoroughly ,  and  1  am  enclosing  copy  of  their 
report  on  your  scheme. 

I  also  return  your  papers  and  photostats

Iir.  Edison  would  like  to  havo  you  hear  in 
mind  the  fact  that  you  arc  being  carried  on  his  pay- 
roll-  Of  coarse,  he  heo  not  forgotten  that  bocre- 
tary  .Daniels  has  authorized  this,  hut  it  swells  tne 
'  amount  of  Ur.  iSaison’s  expenoos  which  come  out  of 
tho  spooial  appropriation.  2he  point  of  tnis  is 
that  if  you  take  a  Commission  in  the  .army  or  iluvy,  that 
would,  automatically  take  you  off  our  pay-roll,  as  Ur. 
Edison  understands  it.  Ue  is,  therefore,  doponding

Dear  Sir:- 

Y/ith  reference  to  your  telephone  oonversa- 
tion  this  date  with  Ensign  Van  Dyfce  of  the  Haval  district 
Base,  I  am  pleased  to  submit  the  following  informat 
in  regard  to  the  relative  ranges  of  audibility  of  a 
submarine  running  submerged  at  a  speed  °f  ^SLa^of  ten 
and  an  ocean-going  cargo  ship  running  at  a  speed  of  ten 
knots.  It  is  apparent  that  the  range  of  audibility  of 
any  sound  in  the  water  will  vary  with  the  type  of 
apparatus  employed  in  the  detection  of  that  sound. 
Accordinslv  there  are  included  ranges  of  audibility 
for  both  mechanical  and  electrical  d®£ethe°t 
•i-ViR  latter  'beinff  the  more  sensitive  of  the  two.  in  an 
oases  the  ocean-going  cargo  ship  will  produce  a  greater 
noise  than 'the  submarine  .^-Imder  °£din??;«  ohaertar  to" 
ditions  a  mechanical  typeAwiXi  enable  the  °^seiver 
ns  tact  the  sound  of  the  submarine  running  submerged  at 
a  speed  ol  K  knots  at  a  distance  of  2000  yards;  will 
detect  the  sound  of  an  ocean-going  cargo  a^P  running 
at  a  speed  of  ten  knots  at  a  distance  of  12, 000  yards. 
Under  like  weather  conditions  an  electrical  apparatus^ 
which  will  enable  an  observer  to  detect  the  sound  or  a 
submarine  running  submerged  at  a  W«d  *">*8  an 

a  distance  of  10,000  yards,  will  detect  the  sound  of  an 
ocean-going  cargo  ship  running  at  ten  knots  at  a  di 
tanoe  of  40,000  yards. 

All  the  above  comparative  data  is  based  upon 
the  assumption  that  there  are  no  other  vessels  in  the 
vicinity  of  the  observing  ship  to  interfere  witn  the 
tection  of  the  submarine  or  ocean-going  cargo  ship . 

Range s  will  also  vary  with  the  different  types  of  ship 
^nd  submarines,  and  with  individual  °V«r^tions 
given  above  are  the  averages  of  many  observations, 
ft  is  hoped  this  information  will  be  of  value  to  you.

My  dear  Mr.  Ediaon: 

Replying  to  your  letter  of  Sept. 
12th,  1918,  in  which  you  refer  to  the 
U.S.S. SACHEM,  in  dry  dook,  and  aak  if 
it  will  be  poaaible  to  exchange  her 
for  a  aimilar  boat  of  about  the  same 
length  but  capable  of  a  higher  speed, 

I  have  to  say  that  no  vessel  of  this 
character  ia  now  available,  the  SACHEM 
being  a  better  vessel  than  any  other 
available.  If  at  any  time  a  fast  ves¬ 
sel  possessing  the  other  characteristics 
undoubtedly  required  to  make  the  vessel 
of  use  to  you  becomes  available,  I  will 
have  your  request  in  mind  and,  if  possi¬ 
ble,  make  the  exchange  you  request. 

Sincerely  yours.

I  aioloao  herewith  ocoloa  of  the  discussion  of  ny  nation  to  abolish 
the  standing  technical  oonmitteoB  of  the  Board. 

Sines  -Kim  X  hare  rooeived  Mr.  Eilson's  oounants,  rending:  "Bood; 
now  they  will  got  results."  Alee  a  letter  from  Prof.  Richards,  reading  In 
part:  "I  did  not  receive  ytnr  letter  of  September  18th  after  my  return  here 
after  our  Saturday  meeting.  Yea  will  understand,  therefore,  that  I  had  had 
no  notice  That  waa  the  principal  reaoon  why  I  urged  that  more 

time  be  given  to  consider  it,  and  not  that  I  was  greatly  opposed  to  it." 


Bstraot  from  notae  taVsn  at  Mating  of  Haval  Consulting  Board 

held  on  September  21,  1916. 

Relative  to  proposition  of  Hr.  Lswrenoe  Addloks  to  abolish 
the  ponnanant  teohnloal  committees  of  the  Board. 

**-  WltfcRi-v  1  have  been  of  the  opinion  for  some  time  that  our  stole  OamittM 
sratea  ns  wrong,  and  in  the  last  four  weeks  X  hove  token  ooeaelon  to  dlsoae* 
this  with  quite  a  number  of  members  and  have  come  rather  to  the  oonolmlou  nn 
la  this  proposed  motion  I  was  simply  making  expression  of  a  generul  apjalan. 

I,  therefore,  offer  the  following  motiont 

That  all  present  standing  teohnioal  oonmitteoe  of  tha  Board 
be  heresy  aonliahed  and  that  eaoh  new  problem  be  hereafter  entrusted 
to  ths  msmber  m  the  opinion  of  the  Chairman  or  hia  delegate  best 
qualified  to  deal  with  it  at  the  time  being. 

In  presenting  that  motion  I  have  several  things  in  mind.  la  tha 
flret  plaoe  our  present  eonmlttee  systan  imposes  certain  hacdl caps  ii 
Offort,  and  It  seems  to  me  that  tha  worit  of  this  Board  is  being  done  at  the 
praeant  time  by  individuals.  We  were  chosen  as  individuals  in  thaftrtt  ygaoo 
Md  I  do  not  think  we  work  well  on  oonmittees.  1  do  not  balls**  that  mm  a?  «• 
aould  say  at  a  moment's  notloe  Just  what  oommlttees  he  is  a  amber  af  • 

There  are  other  objections  to  the  oonnlttee  system.  Va  hhould 

the  game  acoordlug  to  the  rules,  and  that  mesne  that  under  the  prwMmt  ayetmt'  ■■  ■■■'■  :vvrr 
If  u  problem  eones  up  it  should  be  referred  to  the  chairmen  of  the  apyswprt— a 
eamalttee.  How  let  us  suppose  that  Ur.  Hunt  for  example  wore  r  lull  aw  of  the 
fuel  handling  ooamittee.  Let  us  supposs  that  a  rsoomaeudatlon  easaa  lit  haiW  for

problem  Itself  to  be  referred  to  Him  because  be  sayo  be  does

yropoao  to  send  the  erne  question  to  three  different  people,  getting 
independent  opinions,  end  that  information  *111  ccme  to  me-  How  that  oaa 
be  successful  only  if  Admiwl  Smith  knows  Who  is  who  and  What  it  What.  I 

went  to  see  the  schedule,  I  want  to  know  how  they  arr,  going  to  write  it 
down,  what  i.r.  the  obaraoter  of  questions  for  whioh  such  and  Euoh  a  »»  , 
is  going  to  he  nominated.  I  Inw  wall  enough  a  c0.Ms.7ay  proposition  would 
come  to  mo  because  there  is  nobody  else  that  I  Idiot;  of  knows  anything  about 
it,  and  if  it  was  a  belt  conveyor  it  would  go  to  Hr.  Robins. 

lot  them  present  that  liet  at  the  next  meeting  end  then  we  oaa 
deside  as  to  tho  working  of  the  thing  on  the  plan  Whioh  he  proposes.  At 
say  rate  I  do  not  want  to  see  tho  committees  abolished  to-day,  but  1  do 
went  to  authorize  Hr-  Brunton  or  Whoever  passes  out  these  things,  to  use 
'  that  procedure  as  suggeeted  at  their  discretion. 

«r.  X  would  like  to  answer  a  oouple  of  Hr.  Miller's  points.  In 

tho  first  plaoe  the  object  of  abolishing  present  committees  1b  really  to 
relieve  Admiral  Smith  and  Hr.  Brunton  of  their  present  embarrassment  in 
goirg  round  the  ohalrman  of  the  eormittee.  By  abolishing  that  position  of  the 
chairman,  It  allows  each  question  to  ba  dealt  with  on  its  individual  merlte. 

Sot  as  to  the  question  of  a  committee  to  deal  with  oaoh  Individual  case,  that 
16  really  what  I  have  in  mind,  hut  I  think  it  is  wiser  to  allow  the  member 
to  be  selected  to  deal  with  the  problem  end  let  him  assooiato  with  himself  * 
such  members  us  he  waste  for  that  particular  thing.  He  oaa  ask  other  members 
to  deoide  with  him  or  he  can  decide  he  wants  to  do  It  oil  himself.  She  present 


a  down  whoever  is  dealing  out  the  problems.  Ea  either 

has  to  u3e  Marions  W  of  dipleg  or  «  the  -*  *  off9Dililie  8C“9- 
tody  end  it  is  to  prevent  that  that  I  Bring  the  serolution. 

Hr.  Surewgi,  It  is  the  recommendations  5*  wMoh  carry  no  particular 
'ffiioro  are  few  matters  which  have  had  any  weight  Whatever  wittr

The  Secretary  told  me  today  that  he  wanted  me 
to  go  up  to  Orange  and  have  a  conference  with  Lr. 
Edison  so  as  to  get  information  regarding  i,ir  .  Edison  e 
experiments  with  a  view  to  getting  quick  action 
thereon  also  to  get  material  for  the  Secretary  s 
annual  report . 

I  can  leave  here  almost  any  night  and  be  in 
Orange  by  office  hours,  say  ten  o’clock  in  the 
morning  the  next  day  and  spend  as  mchofthe  ^yor 
as  many  days  as  Ur.  Edison  wants,  bin.  I  think  that 
he  can  tell  me  all  he  wants  to  impart  in  a  very 
short  time. 

Will  you  please  arrange  with  Ur.  EdJsontheaay 
that  will  be  most  convenient  to  him  and  either  call

To  the  members  of  the  Naval  Consulting  Board: 

In  accordance  with  the  Board's  decision,  our  next 
meeting  will  be  held  at  Aberdeen,  lid, ,  on  Saturday,  October 

Members  from  Washington  should  take  the  B.  &  0. 
train  leaving  at  7.40  A.M.,  reaching  Aberdeen  at  9.31. 

Other  members  who  spend  the  night  at  Baltimore  or  arrive  there

which  leaves  Baltimore  at  8.35  Camden  Station,  or  8.40  at 
Mount  Royal  Station. 

There  is  another  train,  on  the  Pennsylvania,  which 
leaves  Baltimore  at  8  A.M.,  reaching  Aberdeen  at  3.41,  but  I 
am  unable  to  ascertain  the  distance  between  the  Pennsylvania 
and  B.  &  0.  Stations  a  t  Aberdeen,  and  would  therefore 
recommend  if  any  members  should  reach  Baltimore  by  the  Penn¬ 
sylvania  R.  R.  they  transfer  to  the  B.  &  0,  R.  R.,  Mt.  Royal 
Station,  a  short  ride  by  taxicab.

New  York,  H.  Y.,  Ootober  10,  1918. 

Thomas  A.  Edison,  Esq,. , 

Chairman,  Haval  Consulting  Board, 
West  Orange,  H.  J. 

Bear  Mr.  Edison;  7 

You  probably  know  that  X  have  reoently  returned  from  a  long  stay 
abroad,  three  months  of  which  were  in  the  general  war  zone,  having  been 
through  the  Mediterranean  and  the  English  and  Iriah  Channels. 

I  brought  back  several  fairly  definite  problems  Whioh  I  have  out¬ 
lined  to  the  Board;  but,  owing  to  your  abBenoe  from  the  meetings,  they  may 
not  have  reached  you,  and  I  thought  you  might  be  interested  to  hear  of  them. 

When  the  periscope  is  sighted  it  would  be  desirable  to  have  a 
shell  whioh  oould  be  put  in  an  ordinary  3'1  rifle,  Which,  upon  reaohing  the 
water,  will  light  a  torch;  butn  not  less  than  S  mixruteB.  The  object  of  this 
is  to  place  a  light.. in  the  ocean  where  the  depth  bomb  should  be  dropped  Whan 
the  destroyer  has  time  to  reach  the  spot. 


A  destroyer  oooasionally  sights  a  periscope  inside  its  normal  turning 
of  700  yards,  Whioh  means  that  it  has  to  go  through  a  double  evolution  to  reach 
the  spot,  as  it  oannot  turn  directly.  In  this  connection  it  would  be  desirable 

Thoa.  A.  Edison  -  Sheet  #8.  A-264  -  Oet.  10,  1918. 

to  fire  a  normal  depth  bomb  from  a  gnu  with  a  maodmum  range  of  700  yards.  . 

This  is  now  done  on  a  very  small  seals  by. the  T  guns  now  mounted  on  our 
ohasers,  the  can  gaining  the  depth  charge  being  bolted  to  a  mandrel  which 
is  inserted  in  the  gun  .  It  is  also  being  done  on  the  British  ships  for 
perhaps  200  yards,  but  the  gun  tends  to  hide  so  severely  as  to  damage  the 


Considerable  success  has  attended  the  hunting  of  submarines  by 
night  by  a  submarine.  In  this  case  the  anew  is  on  the  surface  and  is 
destroyed  by  a  torpedo.  She  effectiveness  of  the  torpedo  could  be  greatly 
increased  if  it  were  arranged  so  that  it  could  be  magnetically  detonated  in 
case  it  missed  its  nark  hot  oame  within  a  reasonable  distance.  Captured 
German  torpedoes  indicate  that  the  enemy  already  possesses  such  a  device. 


While  immense  success  has  attended  the  use  of  a  mine  barrage  in  the 
English  Channel  and  Horth  Sea,  the  perfeot  mine  is  yet  to  be  devised.  What 
is  desired  is  a  mine  Which  will  stand  a  5  knot  tide  and  maintain  an  approximately 
equal  submersion  at  all  stages  of  tide.  She  mine  need  not  come  to  actual 
contact  with  the  object  to  be  destroyed,  as  it  has  a  sure  range  of  action  of 
certainly  20  ft.  The  present  mines  have,  as  you  doubtless  know,  tentacles  of 
bronze  firing  by  voltaic  action,  but  apparently  they  have  much  trouble  with  the 
slack  on  the  anchorage. 


One  difficulty  attached  to  the  use  of  listening  devioes  is  the 
terrific  noise  and  possible  permanent  injury  to  the  listener  in  case  he  happens 
to  be  using  the  devioe  when  a  depth  bomb  is  destroyed  in  the  vloinity.  A 
deviae  Whioh  would  automatically  suppress  these  abnormal  heavy  waves,  particularly

In  the  meohanloal  llBtening  device,  1b  desirable. 
rraa  op  MsgmmG  detioes  on  air  setts  ; 

The  general  problem  of  making  available  the  present  listening 
devloes  in  connection  with  either  the  dirigible  or  a  seaplane  haB  great 
possibilities.  This  is  a  problem  on  which  very  little  has  been  done  as  yet. 
The  advantage  over  a  boat  is  that  the  enemy  is  unable  to  hear  anything 
himself,  whereas  an  approaohing  destroyer  gives  him  ample  warning.  The 
idea  would  be  to  use  the  air  ships  as  marker  buoys,  the  actual  depth  charges 
being  released  by  surface  oraft. 

Yours  very  truly.

Dear  I.;r .  Addicks: 

I  have  rocelvod  your  letter  of 
the  10th  inBtant,  end  will  reply  seriatim: 

f.’.Ai< SiiKLL: 

It  seems  to  me  there  should  be  no  diffi¬ 
culty  in  this.  A  regular  Coston  Light  (Calcium 
BhoBphide }  could  be  combined  with  a  regular  'shell. 

DaCX  GUli : 

it  should  not  require  much  engineering 
ability  to  cushion  the. stress  of  the  gun  over  several 
foot  and  distribute  the  stress  over  a  considerable 
area  of  the  boat. 

MASHJSI  IQKi'iiDO  LAiJiiAlOi. : 

1  doubt  if  the  Germans  have  an  effective 
device  of  this  kind. 

LILfiL.lilO  PLY  1C 6  CUT-OUT: 

In  my  .opinion,  the  only  effective  way  to 
prevent  injury  to  the  oar  i6  the  throwing  overboard 
of  a  small  (say,  4  pound)  bomb  at  the  eame  time,  or 
two  or  three  seconds  before  the  main  depth  bomb.  1’he 
small  bomb  should  explodo  on  touching  the  water,  i'his 
could  be  heard  over  a  largo  area  and  givo  sufficient 
time  to  withdraw  the-  listening  tubes. 

She  other  problems  aro  somewhat  out  of  my 
line.  One  of  our  troubles  hoio  is  that  the  Ilavy 
people. are  non-receptive  of  uny  ideas  vhatevor  if  they 

are. put  forth  by  civilians. 

I  am  much  obliged  to  you  for  sending  tho  informa¬

Hy  dear  friend  Braehear: 

Last  year  you  were  good  enough  to  lend 
mo  a  Fiske  iiange  Finder  to  be  .used  in  some  of  my 
experiments  for  our  Uncle  Semuel.  it  came  m  veiy 
useful,  and  os  that  phase  of  my  wort:  nts  gone  as  far 
as  X  cun- rush  it,  I -um  now  going  to  roturn  tno  instru¬ 
ment  to  you.  '  I  have  reported  to  the  powers  than  bo, 
but  whether  anything  will  ever  como  o±  if  goodness 
only  knows.  '  Anyway,  there  is  one  thing  1  am  sure  of 
and  that  is  my  sense  of  thankfulness  to  you  ^or  your 
willing  readiness  to  holp  out. 

X  have  been  plugging  away  on  experiments 
for  Uncle  8am  ever  since  January  of  last  year,  and  am 
still  at  it.  it  has  given  mo  a  lot  of  new  tilings  to 
think  of  and  X  have  on joyed  tho  work. 

If  you  ever  happen  to  be  down  in  this- direc¬ 
tion.  don't  fell  to  drop  in  and  see  me.  ihe  latch 
string  is  always  out  to  you. 

i'.ith  kind  regards,  1  remain.

My  dear  Mr.  Meadoworoft: 

I  take  pleasure  in  acknowledging  your  letter  of  the  16th 
forwarding  a  copy  of  the  report  of  Captain  Harris  concerning 
the  test  made  with  the  sea  anohor.  X  will  forward  that  to 
the  oorreot  office. 

I  have  been  talking  over  the  result  of  my  visit  to  Mr. 

Edison  and  it  has  been  suggested  that  Mr.  Edison  make  up  a 
listening  device  suitable  for  installation  on  a  submarine 
ohaser  and  send  the  same  to  be  attached  to  one  of  the  vesselB 
now  located  at  New  London  for  a  series  of  trials  in  connection 
with  submarines.  I  was  so  much  impreBBed  with  the  fine  me¬ 
chanical  work  and  simplicity  of  design  that  I  would  like  very 
much  for  it  to  be  tested  in  comparison  with  other  devices  es¬ 
pecially  as  it  requires  no  alteration  in  a  hull  more  than 
fitting  a  spar  out  from  the  bow. 

If  this  meets  with  Mr.  Edison's  approval  pleaBe  let  me 
know  right  away  and  I  will  forward  the  SfJheer  plan  of  a  sub¬ 
marine  chaser  so  that  he  can  get  the  correot  proportion. 

I  am  also  taking  steps  to  get  an  order  for  one  to  be  placed 
either  on  a  transport  or  a  vessel  being  built  under  the  cognizance 
of  the  Emergency  Fleet  Corporation. 

X  am  sure  that  if  the  test  at  New  London  shows  any  good 
result  that  we  could  put  one  on  a  transport  and  obtain  much 
quioker  results  than  oould  be  done  by  waiting  for  a  ship  now 
being  built. 

I  am  also  taking  up  the  other  questions  that  I  looked 
over,  with  the  idea  of  plaoing  one  into  immediate  service  for 

actual  trial  at  sea.

hear- Admiral  B.  Strother  Smith,  U..S.1I., 
Levy  Department, 

ii  ashing  ton,  D.  C. 

My  dear  Admiral: 

I  hove  rocelvod  your  letter  of 
October. 19th.  1  oan' t  spare  the  mon  to  take 
the  apparatus  to  lieu  London  to  listen  for  sub¬ 

Perhaps  1  did  not  moke  myself  clear  in 
our  conversation,  but  lot  me  soy  once  more  that 
the  apparatus  is  made  only  to  listen  for  torpodoo.s 
and  was  never  intended  for  detecting  submarines. 

If  real  progress  is  to  be  inode  I  should 
have  an  order  for  four  9  foot  Bea  anchors  and  four 
10  foot  sea  anchors  with  the  necessary  ropo;  alBO 
'  for  two  booms  and  listening  rods;  with  permission 
to  put  at  least  one  listening  device  and -soa  anchors 
on  a  cargo  boot  non  carrying  coal  from  Lorfolk  to 
lien  England.  This  will  not  hold  up  the  cargo  boot 
a  single  minute. 

?hen  1  propose  to  have  the  old  bhitohouse 
torpoao,  (of  which  our  Government  has  many  at  bowport), 
shot  out  somewhere  along  the  Coast  in  heavy  weather 
and  do  this  many  times  and  actually  ascertain  what  can 
bo'  done' to  hear  and  ovoid  them.  I  am  certain  that 

no  torpedo  con  move  within  a  mile  of  the  cargo  boat 
nithout  the  boat  knowing  it,  no  matter  how  stormy  the 

tthen  I  have  done  this,  I  will  take  up  the 
question  of  detecting  the  submarine  itBolf.  I  make 
■no  claims  as  to  this  as  1  have  never  worked  on  it. 

The  oleanlst,  quickest  way  for  tho  whole 
thing,  if  the  Secretary  will  twst  to  my  discretion, 
is  for  him  to  £ivo  mo  a  letter  authorizing  me  to  do 
what  is  above  stated,  and  with  that  letter  I  can  got 
tho  things  I  want  and  get  right  on  the  Job. 

.Yours  sincerely.

a  better  one. 

I  find  that  there  is  a  definite  relation  between

power  a  machine  will  take  and  give  a  given  lift  per  horse¬ 
power;  in  other  words,  for  a  desired  lift  per  horse-power 
increase  of  diameter  is  necessary  in  order  to  be  able  to 

use  additional  horse-power. 

I  wish  to  soy  again  how  much  X  appreciated  your

My  dear  Mr.  Edison: 

I  gathered  together  what  propellers  I  oouia  find  of 
from  20  to  22  inches  diameter  (v/hioh  is  the  size  for  motor 
sailers)  and  tried  them  for  pitch.  They  are  all  cast  from 
the  same  pattern  and  to  my  ear  appeared  to  be  about  the  same 
pitch,  that  is  about  C,  but  they  are  so  full  of  prominent 
overtones  that  I  oould  not  decide.  So  I  got  my  friend,  Mr. 
May land,  who  makes  all  the  bells  and  gongs  for  the  orchestras, 
to  come  in  here  with  his  standard  bars  and  listen  to  them 
and  he  found  one  that  he  pronounced  to  be  C#.  He  says  that 
to  raise  the  pitch  we  will  have  to  take  the  pattern,  thicken 
up  the  blades  with  wax,  and  cast  a  special  wheel  which  we 
can  easily  do,  if  you  wish  it.  I  suppose  that  when  the  shaft 
is  put  in  and  bolted  it  will  change  the  pitch  of  the  combina¬ 
tion  but  have  not  tried  that  yet. 

■Yill  you  Please  let  me  know  if  you  will  want  the  bear¬ 
ings  babbitted  or  Just  bored  for  a  running  fit,  and  whether 
you  need  a  stuffing  box  in  case  the  wheel  is  to  be  run 
immersed  in  water.  Also  please  tell  me  about  how  long  you 
want  the  shaft  and  if  you  need  a  coupling  flange  on  it. 

I  hope  to  < 

:  down  to  Orange  in  a  few  days, if  possible.

Ho  doubt  you  have  been  plugging  away  right  along, 
and  you  will  never  stop  plugging  until  you  die  and  go  to 
heaven,  as  I  am  sure  you  will,  for  the  devil  would  no.  have 
anything  to  do  with  you.  I  am  certain  Ox  onethinghow

thoro  will  he  a  strike  organised,  and  then  well,  1 

will  not  say  what  will  happen! 

Aside  from  this  pleasantry,  I  am  delighted  to  know

you  some  idea  of  the  fun  we  are  having  in  the  use  of  this

Just  now  I  am  taking  great  interest  in  the  ^ca¬ 
tion  of  the  returned  disabled  soldiers,  particularly  in 
industrial  lines,  and  although  I  will  be  seventy-eight  yeais  ^ 



of  age  this  day,  one  month  henoo,  I  would  like  to  live  a  few 
years  longer  to  help  these  good  follows  who  have  done  their 
best  to  knock  h -  out  of  the  Kaiser. 

My  only  Alma  Mat  or  was  an  old  rod  brick  school 
house,  and  if  it  were  standing  to-day,  X  could  pick  out  the 
brick  which  I  leaned  against,  with  my  hand  on  my  forehead, 
and  - !  after  smoking  my  first  and  last  cigar.

Hear  Admiral  Goo.  E.  Burd, 

United  States  Ilavy  Yard; 

Hew  York,  H.Y. 

My  dear  Admiral: 

I  have  received  your  favor  of  October 
24th,  and  am  much  obliged  to  you  for  your  courtesy  and 
prompt  attention  to  the  matter  of  the  propellers. 

I  have-  something  Bpecial  in  mind  that  I  would 
like  to  takH  to  you  about,  and  can  explain  it  better 
in  person  than  I  could  by  letter,  so  I  am  going  to  wait 
until  you  come  over  to  Orange  to  make  me  that  promised 
call.  -  I  hope  you  may  be  able  to  find  time  in  the  near 
future . 

Yours  sincerely. 

October  28,1918.

We  are  Republicans  loyal  to  the  spirit(  of  the 
Republican  Party,  but  in  this  hour  we  are  willing  to 
subordinate  our  partisan  to  the  demands  of  the  World's 
needs.  We  must  not  have  a  divided  council.  It  is 
for  us  to  show  the  people  of  the  whole  World  that  we  stand 
by  the  President  in  his  war  aim. 

The  election  of  a  republican  Congress  will  be 
construed  by  our  enemies  and  opposed  by  our  friends  as 
a  sign  of  internal  division.  We  must  lay  aside  our 
political  feelings  for  the  moment.  America  should  uphold 
the  President's  needs  by  giving  him  a  Democratic  Congress 
which  will  spell  to  the  World  United  America. 

The  result  of  the  approaching  election  will  be 
scanned  by  the  German  enemy  for  anything  for  which  it  can 
disguise  into  a  sign  for  divided  support  for  the  president 
and  America.  We  deem  it  an  honor  in  this  hour  of  crisis 
to  vote  for  our  Country.

with  your "rig. 

Her  number  is  1206.  The  engine  is  now  in  her  hut 
it  v;ill  he  n  small  matter  for  us  to  take  it  out  if  she 
will  suit  vou.  If  you  will  let  me  know  about  this,  I 
will  got  the  Department's  permission  to  take  out  the  en¬

Dear  Mr.  Plantiff:  Atten:  Mr.  Plantiff; 

We  have  rooeivoa  from  your  Company 
the  enclosed  bill  for  one  Chassis,  which  was  sent  to 
Mr.  Edison  by  order  of  Mr.  Ford  lest  Juno.  It  was 
originally  intended  by  Mr.  Ford  that  there  should  bo  . 
no  oharare  to  Mr.  Edison  for  this,  as  he^was  going  to 
make  Borne  experiments  with  it  in  connection  with  war 
work.  _ 

Mr.  Edison  wants  me  to  say  that  inasmuch  as 
?.ir.  Ford  want  into  the  manufacture  of  small  tanks,  he, 
Mr.  Edison,  would  not  commence  any  experiments  on  this 
line.  He,  thereforo,  wantB  to  return  the  Chassis  to 
vour  Comoany.  Ho  work  has  ever  beon  done  on  it.  and 
it  is  in  exactly  the  same  condition  as  when  we  recoi\ed 

Mr.  Edison  would' like  to  return  the  Chassis, 
but  we  are  vory  ohort  of  men  and  have  no’ one  atjprosent 
by  whom  we  could  send  it.  .  Can  you  send  one  of  your 
men  over  to  drive  this  Chassis  book  to  your  bond  Island 
Cit”  plant?  If  so,  I  shall  be  obligod  if  you  will 
kindly -oull  me  up  on  the  'phone  and  say  when  we  can 
expeot  your  man.  You  had  better  give  hime  a  letter 
authorizing  him  to  reaoivo  it,  so  that  we  will  know 
we  aro  delivering  it  tothe  right  party.1 

When  the  Chassis  is  returned  to  your  V.orks, 

I  presume  the  enclosed  bill  .will  be  oanoolled,  except 
the  items  of  gas  and  oil. 

With  kina  regards,  I  remain, 
your 8  vory  truly.

November  6,  1918. 

My  dear  Mr.  Mesdoweroft: 

I  am  enclosing  you  a  copy  of  a  letter  signed 
by  the  Secretary  to  Mr. Edison  in  regard  to  his  experi¬ 
ments  on  torpedo  listening  device  and  kite  rudder. 

The  Secretary  has  been  extremely  busy  the  last 
two  or  three  weeks  and  I  laid  before  him  all  the  data 
necessary  for  hi3  information,  and  prepared  the  letter 
this  morning,  which  has  been  approved  and  signed  by  him. 

You  will  note  in  the  letter  that  orders  will 
be  given  to  the  Bureau  of  Construction  and  Repair  for  the 
necessary  instructions  to  be  given  to  the  New  York  Navy 
Yard  for  the  manufacture  of  the  sea  anchors. 

I  have  no  doubt  that  you  have  full  specifications 
and  instructions  ready  for  the  New  York  Yard  as  the  submarine 
will  have  to  make  many  changes  in  her  torpedo  tubes  and  I 
would  like  to  know  about  how  long  it  will  take  Mr .Edison 
to  make  his  preparations. 

In  Mr.  Edison's  letter  to  me  he  stated  that 
practically  all  he  needed  was  authorization.  I  have  en¬ 
deavored  to  find  a  merchant  ship  upon  which  he  could  install 
his  listening  device  but  could  not  find  one  as  the  Navy 
Department  does  not  control  coasting  vessels. 

The  Harada  is  a  large  sea-going  yacht  and  she 
oould  be  sent  to  Hoboken  at  almost  any  time  Mr.  Edison 
desires  and  when  the  experiment  is  ready  I  will  come  up 
and  go  over  all  the  preliminarys  and  see  that  no  hitch 
is  encountered  and  that  the  experiments  will  show  all 
that  is  desired  and  full  data  taken. 

I  have  had  considerable  experience  in  arranging 
for  trials  and  have  found  that  unlesB  a  very  careful 
pre-arrangement  is  made  there  is  always  some  loose  link 
that  invalidates  the  whole  work  done. 

navy  department 


I  am  directed  by  the  Secretary  to  keep  in 
personal  touch  with  this  trial  and  will  you  please  use 
long  distance  telephone, telegraph  and  letters  so  that 
I  am  kept  in  close  touch  with  it. 

Hoping  this  will  'be  entirely  satisfactory  to 
Mr.  Edison  I  am  with  kindest  regards.

Hovember  6,  1918. 

My  dear  Mr.  Edison: 

I  hope  you  will  pardon  my  seeming  neglect 
for  the  past  two  weeks,  hut  as  you  know  I  have  been 
extremely  busy  and  away  from  Washington  part  of  the 

On  my  return  I  have  taken  up  all  the  pre¬ 
pared  data  on  your  idea  of  avoiding  torpedo  attack  by 
the  use  of  sea  anchors  and  a  listening  device  for  tor¬ 
pedoes.  I  find  that  it  is  extremely  difficult  to  obtain 
the  services  of  a  oar go  boat,  but  if  you  can  do  so  and 
■will  let  me  know  what  steps  it  is  necessary  for  me  to 
lake  I  will  give  it  my  personal  attention,  and  you 
have  ’my  full  authorization  to  proceed  with  the  manufacture 
of  such  sea  anchors  as  you  may  need  and  when  you  are  ready , 

I  will  direct  a  submarine  to  proceed  to  sea  for  the  pur¬ 
pose  of  firing  torpedoes. 

The  modern  submarine  is  not  fitted  for  firing 
the  Whitehead  torpedo,  'out  with  slight  ^anges  csn  be  made 
to  accommodate  this  weapon.  The  services  of  ^heHarada, 
a  large  sea-going  yacht  can  be  obtained  much  quicker  than 
a  cargo  boat  and  she  could  be  sent  V^oh  nearer  your  labora¬ 
tory  for  the  purpose  of  fitting  the  listening  device  than 
a  vessel  engaged  in  traffic  along  the  coast. 

I  presume  you  will  make  a  listening  device  in  your 
laboratory  and  desire  the  sea  anchors  and  nec essary  rope  to 
be  furnished  from  the  Hew  York  Havy  Yard.  I  have  directed 
the  Bureau  of  Construction  and  Repair  to  issue  the  necessary 
orders  for  this.  Will  you  please  let  me  know  what  I  can  do 
further  in  this  matter. 

Sincerely  yours,

Naval  Consulting  Board 


Nov.  11,  1918. 

The  Chairman  requests  me  to  issue  the  following 

notice: - 


Dear  Sirs: 

In  view  of  the  ending  of  the  War,  the  question 
of  further  expenditure  in  the  work  you  may  be  doing 
should  come  up  and  be  decided  at  the  meeting  at 
Washington  next  Saturday,  November  16th,  In  the 
meantime  please  use  your  judgment  as  to  the  wisdom 
of  continuing  expenditure. 

W.  L.  Saunders 

It  is  hoped  that  every  me  nriber  of  the  Board  will 
be  present  at  Saturday’s  meeting. 

Yours  very  truly, 

Thomas  Robins, 



November  14,1918. 


Hon.  Josephus  Daniels, 

The  Secretary  of  the  Navy, 
Washington,  D.  C. 

My  dear  Mr.  Daniels: 

This  is  in  reply  to  your  letter 
of  the  6th  instant,  saying  that  it  is  extremely  diffi¬ 
cult  to  got  a  oargo  boat  with  which  to  try  the  torpddo 
experiment;  also  that  considerable  changes  will  have 
to  be  taede  in  the  torpedo  tube  to  fire  a  Whitehead 
torpedo.  .  , 

Let  me  Say  that  this  is  another  characteristic 
sample  of  the'  misinformation  furnished  you  by  Department 
chiefs.  I  was- informed  and  found  out  myself  at  Newport 
that  any  submarine  they  had  there  can  fire  a  Whitehead 
torpedo  without  any.  ohange. 

To  mote  sure,  I  got  Newport  on  the  telephone 
after  receiving  your  letter,  and  had  .this  corroborated. 

^hey  positively  asserted  that  no  change  would  be  necessary. 
It  would  be  strange  if  it  were  not  so,  as  the  Government 
has  a  large  stook  of  Whitehead  torpedos  in  addition  to 
the  Bliss  type,  I  am  told. 

Regarding  obtaining  a  cargo  boat,  I  havo  already 
stated  that  I  oould  use  any  coastwise  oargo  boat  without 
delaying  the  boat.  Let  me  say  in  addition,  that  in  the 
yards  around  new  York  and  vioinity,  there  is  turned  out. 
every  day  a  oargo  boat.  All  these  boats  have  to  have 
their  trials  trips,  and  I  oould  go  on  one  of  them  to  carry 
out  my  experiments.  I  have  now  waited  eight  months  to 
get  trials  of  sea  anchors  *  etc.,  and  I  sm  afraid  if  Smith 
is  to  have  charge  it  will  be  six  months  more. 

If  you  will  authorize  the  Brooklyn  Navy  Yard 

to  make  the  sea  anchors  and  small  mast  for  the 

listener  on  the  bow  of  the  boat,  I  will  go  ahead  as  I  think 
I  oan  gat'  a  cargo,  boat  myself  from  tbe  manufacturers  before 
they  are  turned  over  to  the  Government. 

As  the  War  is  over,  this  JeTioe will be 
unnecessary  to  save  cargo  boats,  hut  I  thinJc  it  will 
'he  of  great  value  for  sailing  in  fogs  and  preventing 
collisions.  If  you  want  me  to  go  ahead,  I  will  aak. 
Admiral  Burd  to  male e  the  small  mast.  He  will  probably 
refer  it  to  -"On,  and  if  you' will  feel  l'ifce  authorizing 
it  as  you  have  authorized  the  anchors,  I  will  go  ahead  and 
put  it  on  a  cargo  boat. 

Yours  sincerely.

■Statement  sent  to  I'ajor  iVilliaia  3~*  Hammer,  U. 
Representing  Inventions  Section,  Jar  Plans  Div 
General  Staff,  Army  ,/ar  College,  who  witnessed 
Helicopter  test  Hovemher  1st,  1011: . 


November  Sth.  191H. 

The  fundamental  object  of  the  helicopter  is  to  obtain  a 
lift  more  than  equal  to  the  entire  weight  of  the  machine. 

That  is,  to  obtain  an  upward  pull  by  means  of  dynamio  action 
of  propellers  greater  than  the  total  weight  of  the  machine 
including  motors,  fuol  and  load  so  that  the  machine  will  be 
forced  upward  and  lifted  into  the  air. 

The  helicopter  that  I  have  designed,  hereafter  called 
Helioopter  Ho.  1,  has  propellers  of  large  diameter  adapted  to 
act  upon  a  large  mass  of  air,  and  the  blades  arc.  designed  to 
approximate  the  action  of  aeroplane  wings  to  obtain  the  ad¬ 
vantage  of  their  lift. 

In  earlier  considerations  of  this  problem  it  was  thought 
possible  to  accomplish  ascension  by  the  simple  reaction  re¬ 
sulting  from  the  downward  acceleration  of  the  mass  of  air  acted 
upon  by  the  propollor. 

The  laws  relating  to  reaction  duo  to  acceleration  of  a 
fluid  (air)  are  perfectly  understood  and  exact  calculation 
can  bo  made  for  obtaining  the  required  lift  for  anyspecifio 
weight  of  machine.  The  conditions  being  that  the  dynamio  re¬ 
action  in  pounds  obtained  per  horse-power  multiplied  by  the 
available  horse-power  must  exceed  the  total  weight  of  the 
machine  and  motor  in  order  that  the  machine  may  rise  from  tho 

The  laws  of  momentum  and  consideration  of  resulting  dis-

token  into  aooouut.  This  requires  a  ooreful  datarrainotion  of 
the  size  of  the  propeller  need,  and  it  must  he  so  chooan  that 
the  weight  of  air  noted  upon  per  second  and  the  velocity  part¬ 
ed  to  the  air  will  five  the  desired  thrust  or  pull,  lift  war 
horse-power  being  proportional  to  the  size. 

It  appears  that  up  to  the  present  it  has  been  considered 
very  important  to  have  a  very  li  -ht  machine  and  very  Ufeht  mot¬ 
ors.  This  is  not  necessary  as  the  lift  obtainable  ith  a  motor, 
that  is  the  lift  por  horse-power,  is  proportional  to  the  c.uan- 
tity  of  air  handled  or  proportional  to  the  size  of  the  propeller 
used.  Heretofore  the  propellers  used  appear  to  me  to  have  been 
too  small  indiameter  for  the  horse-power  designed  for  their  op¬ 
eration.  Hecent  dynamic  research  has  brought  forward  new  and 
most  important  discoveries  whereby  great  advantages  have  been 
obtained  by  the  form  of  lifting  surfaces  used.  The  investigation 
of  supporting  surfaces  for  aeroplanes  has  developed  planes  where 
the  lift  obtained  from  the  upper  and  lower  surfaces  of  the  plane 
nre  not  the  same,  that  obtained  from  the  upper  surface  being 
much  .renter  than  that  obtained  from  the  lower  surface.  The 
resulting  total  lift  is  much  greater  per  horse-power  than  was 
formerly  considered  as  possible  by  simple  dynamic  action. 

in  order  to  avail  of  the  advantages  of  these  discoveries 
and  apply  them  in  a  helicopter  tt  is  necessary  to  know  how  the 
conditions  of  lift  are  affected  when  a  plane  is  rotated  as  the 
blade  of  a  propeller  and  when  the  plane  is  acting  as  a  propel¬ 
ler  blade  to  obtain  results  as  advantageous  as  those  obtained 


by  an  aeroplane  wing.  It  is  also  very  important  to  know  how 
these  results  are  modified  and  influenced  by  the  diameter  of 
the  propeller,  the  size  of  the  propeller  blado,  the  speed  of 
revolution  of  the  propeller  and  the  relation  of  the  si::e  of 
the  propeller  to  the  horse-power  . ith  which  it  is  driven. 

Helicopter  Ho.  1,  is  designed  so  that  it  mi.’ht  be  operated 
to  furnish  practical  data  relative  to  these  various  problems 
and  enable  their  solution,  an'5  particularly  for  obtaining  data 
relative  to  the  relation  of  diameter  to  lift  per  horse-power 
for  the  horse-power  used.  It  is  designed  to  be  operated  with 
20  horse-power  at  100  revolutions  and  sustain  a  lift  of  4000 
pounds  and  withstand  the  unequal  strains  due  to  buffeting  of 
the  air.  It  is  built  entirely  of  steel  oxcspt  the  ribs  of 
th6  propeller  blades  and  the  blade  covering  which  are  of  sheet 
aluminum.  She  design,  nice,  material  of  construction  and 
strength  are  such  os  to  serve  as  a  guide  for  ost? mating  the 
necessary  weight  of  the  whole  and  tho  various  parts  in  future 
designs  and  suggest  desirable  modification  of  design. 

The  experimental  data  furnished  be  t  sts  of  Helicopter 
Mo.  1  show  that  the  aeroplane  wing  lifts  are  obtained,  and  ths.t 
the  lift  per  horse-power  for  a  given  diameter  is  in  excess  of 
that  formerly  thought  nossiblo  to  bo  obtained  by  simple  dynamic 

Although  for  varionu  roasons  it  has  as  yet  only  boon  op¬ 
erated  with  about  six- tenths  of  the  horse-power  for  which  it 
was  designed  it  has  givan  a  lift  more  than  its  own  weight  and 
tho  WBight  of  standard  motors  of  this  horse-power  and  a  surplus 




of  mora  than  tho  weight  of  a  man  and  fuel  (aoe  oppilulation 
of  testa )  . 

Holiooptar  llo.  1  oonslata  of  two  propellers,  one  the 
other,  eaoh  61  feet  in  diameter,  one  he  ins  right  hand,  the  other 
loft,  rotating  in  opposite  directions  in  oporntion.  Tho  power 
transmission  shnftB  are  conoentrio  and  driven  by  two  motors 
whereby  the  torque  is  transmitted  without  load  on  tho  bearings 
or  working  stress  transmitted  through  tha  frame. 

In  operation  there  ia  but  little  if  any  tendendy  of  the 
motive  power  support  to  rotate,  balance  of  the  propeller 
torque  being  more  easily  obtained  than  was  oxpeoted. 

The  propellers  are  designed  so  that  the  centre  of  sunport 
of  the  blade  is  forward  of  the  centre  of  lift  in  order  to  pro¬ 
mote  smooth  action  and  avoid  chattering  (the  practical  working 
is  perfect).  This  gives  a  small  torsional  moment  to  the  tubo 
whioh  cots  ns  tho  oomprossion  momber  or  arm  of  the  propeller 
which  is  holi  at  tho  hub.  This  tube  runs  through  the  blades 
to  which  they  aro  fastened.  Tho  operation  of  the  propnllers 
is  moat  satisfactory. 

The  shabe  of  the  propeller  blade  1b  that  of  Kiffel  wing 
llo.  63.  This  wing  was  selected  booause  of  the  exhaustive 
treatment  of  it  in  "Houvellos  Reoherches  aur  la  Resistance  de 
Ii'Air  et  VAviation,  Paites  au  Laboratoire  D'Auteul",  which 
was  thought  might  prove  useful  in  case  of  being 
observed  during  the  toots  and  would  enable  modification  to  bo 
Intelligently  made.  Wing  Ho.  63  has  only  76£  the  effioienoy 
of  wing  Ho.  32  whioh  I  hope  to  substitute  for  it  and  obtain 


12°  at  the 
a  lift 

blade  should 
about  6°, 

demonstrating  the  faithfulness  of  the  action  of  the  blade  and 
also  giving  very  valuable  date  for  consideration  respecting 
Its  action  in  this  connection  nand  Burgosting  the  great  impor¬ 
tance  of  further  investigation.  This  apparent  angular  loos 
of  power  will  become,  in  my  opinion,  useful  power  for  movement 
when  the  machine  is  not  stationary,  and  during  the  tests  a  side 
v;ind  c.unod  the  machine  to  develops  grant  additional  life. 

Helicopter  Ho.  1  weighs  about  1500  pounds  and  has  an  excess 
weight  of  more  than  300  pounds  which  is  capable  of  being  removed. 
This  excess  weight  is  dud  to  not  being  ablo  to  obtain  standard 
tubing  of  suitable  sis:e  at  the  time  of  construction.  Standard 
Hess-Bright  ball  bearings  are  used  throughout  and  are  entirely 
out  of  proportion  to  the  work  required  of  them.  Suitable  gear 
were  not  obtainable,  so  a  make-shift  set  was  installed  to  save 
time.  Suitublo  gears  would  have  beon  easily  obtained  in  or¬ 
dinary  times. 

The  machine  sot  up  for  testing  is  mounted  on  a  platform  to¬ 
gether  with  its  motors  which  stand  on  a  scales,  the  platform 
resting  on  a  small  ball  thrust  bearing  which  is  between  it  and 
the  scales  so  that  the  machine  is  free  to  rotate.  This  enables 
measuring  any  inequality  of  torqud  of  the  propellers  and  any 
tendency  of  the  motors  to  rotate.  T'e  balance  is  so  perfect 

26$  advontago  in  lift. 

In  a  test,  the  blade  being  set  at  an  angSe  of 
circumference ,  gave  in  operation  at  various  speeds 
fairly  accurately  corresponding  to  the  lift  suoh  n 
give  if  acting  as  the  wing  of  an  aeroplane ,  set  at 



that  the  whole  may  he  turned  with  one  finger. 

The  total  weight  of  machine  and  motors  before  starting  the 
test  is  taken,  being  about  90CX,  pounds,  which  is  rend  on  a  dial 
of  the  scales  graduated  to  10  pounds  and  oari  be  read  accurate, ly 
to  5  pounds.  During  the  tost  the  original  weight  is  reduced 
by  the  amount  of  the  lift  obtained  which  the  scales  continually  , 
registers  and  is  shown  by  the  dial.  As  more  power  is  used 
and  the  lift  becomes  greater,  the  scales  register  less  weight. 
The  machine  during  the  tests  is  operated  by 

calibrated  electric  motors  for  accurately  obtaining  momentary 
power  reading. 

I  enclose  tests,  El  -.(25-19)  -  (26-34)  -  20  -  31  -  SB  - 
E5,  which  explain  themselves,  a  number  of  email  photographs  of 
the  machine  as  operated,  and  curve  sheets  indicative  of  the 
relations  of  diameter  of  propeller  and  lift  per  horse-power

December  2,1918. 

Friend  McGowan: 

Your  Annual  Heport  wa8  received  and  read 
with  muoh  interest. 

In  my  opportunity .of  observation  of  the 
Navy,  you  are  the  only  man  who  has  made  good,  or  that 
took  the  slightest  pride  in  improving  the' navy,. or 
had  any  snap.  I  suppose  this  opinion  is  unjust, 
but  all  my  life  I  have  been  on  the  jump,  doing  many 
things  quick  and  with  great  enthusiasm,  as  you  have 
been’doing  sinoe  the  war.  So  I  have  no  patience  with 
the  dead  personalities  I  have  met  in  the  Navy.  _ They 
all  appeared  to  resent  the  war  as  a  disturbance  of 
their  life  routine,  and  appeared  and  acted  as  if  they 
did'nt  have  any  pride  in  the  Havy,  or  without  the 
push  to  accomplish  things  that  would  add  to  the  Navy's 

They  turned  down  every  project  and  went  out 
of  their  way  to  do  so.  No  one  would  do  a  thing  to 
help,  except  Daniels  and  he  is  powerless  to  get  anything 
done  if  the  Department  heads  disagree. 

I  must  say  the  Havy  boys  are  fine  fellows 
and  one  cannot  help  liking  them,  but  why  they  act  the 
way  they  do  is  a  mystery  to  me. 

I  hope  you  are  in  good  health  and  will  get 
full  public  recognition  for  what  you  have  done. 

Sincerely  yours. 

Hear  Admiral  Samuel  -McGowan ,

you  speak  of  Lieut.  Warren  Stone  Harris,  and 
recommend  his  promotion.  I  will  take  this

haopy  if  your  recommendation  can  be  carried  out. 

I  wish  you  to  know  of  m  a.eep  sense  of 
appreciation  of  your  devotion  to  the  Havy  and 
to  the  cause  of  your  country  in  this  great  war, 
and  for  your  wisdom  and  wise  counsel. 

Always  with  sentiments  of  esteem  and  high

Rear  Admiral  Goo.  2.  Burd , 
Navy  Yard, 

Brooklyn,  U.Y. 

My  dear  Admiral: 

I  am  sanding,  herewith,  blue  prints 
of  a  holder  for  my  listening  device  for  Submarines, 
which  you  kindly  offered  to  have  made  at  the  Navy  Yard. 

You  will  doubtless  remember  that  I  sent 
Ur.  Henry  G.  Wolfe  to  see  you  about  this  when  he  went 
to  the  Yard  to  fix  up  that  small  motor  boat.  Ur.  Wolfe 
is  one  of  the  employees  of  the  Hew  York  Edison  Company. 
They  loaned  him  to  me  for  the  duration  of  the  War,  and 
he  is  now  about  to  return  to  the  New  York  Edison  Co.  at 
loth  Street  and  Irving  Place. 

He  understands  my  plans  about  the  listening 
device  and  perhaps  you  will  not  object  to  his  dropping 
into  the  Yard  every  day  or  two  to  supervise  the  making 
of  the  holder,  shown  by  the  blue  prints.  If  you  will, 
therefore,  drop  him  a  note  when  the  work  is  started,  he 
will  drop  in  occasionally  and  watch  its  progress. 

Yours  very  truly.

Mr.  Thomas  A.  Edison, 

Edison  Labratories, 

Orange,  Hew  Jersey. 

My  dear  Mr.  Edison: 

Since  I  last  heard  from  you,  I  was  'given  the  commission,  but  realiz-' 
ing  the  short  duration  of  the  war,  I  declined  to  accept  it,  to  get  back  into 
work  which  I  consider  more  permanent.  ■ /'T~ 

-w*  V 

X  have  been  assisting  in  some  (fevelopmant  work,  which  I  feel  you 
will  be  interested  in  knowing  something  about,  and  1  will  give  you,  in  a 
general  way,  what  I  have  seen. 

The  very  feeble  current  taken  from  the  wireless  telegraph  aerial 
is  led  into  a  two  stage  andlon  (this  andlon  is,  of  course,  especially  designed 
for  this  work).  From  the  audion  the  amplified  current  is  led  into  a  modified 
head  telejhone,  working  in  front  of  and  very  close  to  a  small  Jet  of  air, 
which  is  under  about  1"  water  pressure  and  escaping  from  a  1/32"  nozzle.  A 
horn  is  placed  so  the  end  of  this  air  jet  Just  enters  the  small  end  of  the 
horn  and  enables  one  to  hear  the  wireless  message  some  forty  or  fifty  feet 
away  from  the  horn. 

Another  arrangement  of  this  air  jet  is  UBed  for  teaitetng-eMd  cooling 
a  very  fine  platinum  wire,  the  heating  and  cooling  of  which  causes  a  sensi¬ 
tized  relay  to  work  so  that  the  relay  operates  a  sounder,  which  causes  a  paper 
tape  to  go  back  and  forth,  under  a  fountain  pen,  and  reoords  the  dots  and 
dashes  very  clearly  on  the  tape. 

Both  of  these  arrangements  work  very  nioely.  This  work  is  partly 
for  the  government  and  is  supposed  to  enable  the  submarine  oables  to  be 
worked  with  very  small  current ,  thereby  increasing  the  Bending  oapaoity  fully 

The  arrangement  of  the  sensitive  air  jet  I  thought  probably  would 
be  of  extraordinary  interest  to  you,  as  it  would  probably  be  possible  to  use 
some  suoh  an  arrangement  in  oonneot ion  with  a  phonograph.  This  application 
would  be  necessary  only  where  and  in  connection  with  a  plan  that  1  have  heard 
of  being  worked  on,  that  of  having  a  hardened  steel,  magnetic  wire,  being 
drawn  in  front  of  an  eleotro  magnet ,  being  produced  by  the  previously  polorr- 
iied  wire- or  disk.  I  assume  you  are  familiar  with  this  arrangement.  1 
have  set  by  the  side  of  this  instrument  and  -saw  the  Jape  reoord  accurately, 
a  message  from  th*  wireless  station  at  San  Diego,  California  and  Key  West, 

I  have  been  told  that  the  Victor  Phonograph  Company  is  working  on  a 
new  instrument,  whioh  they  expect  to  have  out  within  a  year,  along  these  Clines 

ntirrue  in  the  best  of  health, 

Sinoerely  yours,

out  an  air  scheme  similar  to  yours  ana  we  made  Jialf-

Great  and  Good  Friend: 

X  have  not  sooner  acknowledged  your  vary  wonderful 
letter  of  2  December  because  1  have  been  trying  to  be  fashion¬ 
able  and  get  into  the  casualty  list  with  influenza.  Having 
failed  in  this,  I  expect  to  fail  again  in  up  effort  to  tell 
you  how  much  I  appreciate  the  kind  things  you  were  good  enougn 
to  say  about  me  and  rip  work. 

True,  I  have  tried  very  hard.  Likewise,  I  have  done 
the  best  I  could.  But  my  efforts  would  have  amounted  to  little 
or  nothing  if  X  had  not  been  surrounded  by  the  most  efficient 
staff  that  I  think  any  man  over  had  anywhere .  To  them  and  to 
the  generous  encouragement  of  a  few  powerful  friends  like 
yourself  may  be  largely  attributed  such  measure  of  sucoess  as 
I  have  been  able  to  attain. 

If  you  think  that  I  am  camouflaging  in  the  least  degree 
in  the  statement  I  have  just  made,  I  wish  you  could  be  here  some 
day  when  distinguished  visitors  are  looking  me  over  ana  see  me 
show  them  your  photo-rnnh  which  is  at  my  right  hand  and  so  close 
to  me  always  that  I  ggftMally  shake  hands  with  you  if  you 
would  only  let  me.  WhaS  I  tell  people  when  they  exclaim  oyer  my 
having  an  autographed  photograph  of  yourself  is  that  your  in¬ 
scription  is  the  result  of  the  most  remarkable  and  successful 
camouflage  ever  attempted  by  anybody  in  the  i'AVY. 

X  mean  that  I  felt  almost  like  a  confidence  man  when 
I  aocepted  from  you  your  picture  on  which  you  had  written  with 
your  pen:  “To  a  live  wire,  my  friend  Samuel  HoGowan,  U.j.a. 

And  yet,  however  undeservod,  it  accomplished  a  lot  of 
good  because  I  swear  to  you  that  I  have  tried  ever  since  then  to 
aotually  be  a  live  wire  and  thus  keep  you  from  ever  finding  out 
how  far  you  had  over-estimated  me. 

For  the  rest,  I  promise  you  that  I  am  now  trying  anu 
shall  hereafter  continue. to  try  to  live  up  somewhere  near  to 
the  very  high  estimate  expressed  in  your  good  letter  to  which 
this  is  the  reply. 

With  sincere- assurance  of  my  grateful  appreciation  and 
trusting  that  I  may  have  the  pleasure  and  honor  of  seeing  you  when 
you  next  visit  Washington,  I  am  n  ^ 

yours  faithfully.

Uy  dear  Hr.  Baker. ^  ^  tha  it0n;B  m'the  line  of  my  experiments 
for  the  Secretary  of  the  Ilavy  was  locating  the  position  of.  guns 
by  sound  through  the  medium  of  phonographic)  records. 

My  early  experiments  were  made  with  a  shot  gun 
and  guns  of  small  calibre,  but  I  did  not  deem  our  work  complete 
until  tests  were  also  made  to  include  big  guns.  Therefore,  I 
sent  my younsr  men  to  Sandy  Hook.  and. I  am  forwarding  to  you 
herewith  a  copy  of  thB  report  I  have  made  to  the  Secretary  of

whioh  we  have  boon  performing  on  their  orders.  I  have  aokod  Hr.  Byder  to  get 
this  together. 

So  should  go  very  oarefully  ovor  any  orders  which  have  boon  plaood  on 
the  outside  for  work  in  this  oonneotion  and  make  sure  that  all  bills  for  such 
work  have  been  received  and  taken  into  our  account  against  Edison

there  is  the  remotest  possibility  of  these  oonooms  Bonding  us  further  chare™ 
of  whioh  we  are  not  informed  at  the  moment,  will  you  be  good  enough  to  rofor 
suoh  items  to  mo  with  full  information  so  that  I  oan  consult  tho  Legal  Eeport- 
mont  and  arrange  for  letters  to  go  to  suoh  vendors  to  require  a  statement  from 
them  of  thelrohurgoo  against  the  Laboratory  end  got  a  release  from  any  further 

If  thoro  is  any  further  Government  work  being  done  in  tho  Laboratory 
for  Edison  Phonograph  Works,  would  suggest  that  you  consult  with  them  to  asoor- 
tain  whether  or  not  work  should  be  stopped. 

Hr.  Eckert  tolls  me  that  it  is  his  belief  that  tho  Laboratory  was  in¬ 
structed  some  time  ago  to  discontinue  all  work  on  the  "Hark  3-B"  Ordor.  and  l 
understand  from  Hr.  Bydor  that  Hr.  Olson  has  stated  that  no  work  has  boon  done

lir.  Howard  Eckert,  Secretary  of  Edison  Phonograph  Works, 
has  telephoned  me  this  afternoon  that  all  orders  on  which  the  Laboratory 
is  engaged  on  instructions  of  Edison  Phonograph  Works  for  account  of  the 
United  States  Government  must  be  wound  up  as  of  Saturday,  December  28,  1918. 
The  Phonograph  Works  must  render  a  final  account  to  the  Government  within 
two  weeks. 

This  means  that  the  Laboratory  will  have  to  figure  up  the 
final  cost  of  all  of  these  orders  and  bill  the  Edison  Phonograph  Works,  so 
that  they  may  make  their  accounting  to  the  Government. 

I  have  asked  Ur.  Eckert  to  see  to  it  that  the  laboratory  is 

advised  in  writing  regarding  this.

(b)  The  amount  of  sky  covered  by  clouds  in  tenths 

(c)  The  character  of  the  clouds  in  the  sky. 

(For  instance,  the  first  series  of 
observations  the  clouds  in  the  direction 
of  observation  were  dark  Cumulus; 

4/10  of  the  sky  was  covered  with  the 
cloudB;  and  the  general  character  of 
the  clouds  were  medium  and  dark  Cumulus) 

Table  Ho. 7  -  The  brightness  of  the  sky  and  water  are  given 
at  the  same  angle  from  the  horizontal;  the  farmer  above,  the  latter 
below;  the  altitude  is  therefore  designated^plus  and  minus.  For  the 
first  series  of  measurements  the  clouds  in  the  direction  of  observation 
are  gray  Cumulus;  the  time  of  the  observation  for  the  sky  was  "6.11" 
and  for  the  water  "6.12  am.";  the  milliambert  brightness  for  the  sky 
8.05  and  for  the  water  1.54. 

I  believe  that  with  the  above  explanation  you  will  find  no

Dear  Sir: 

Unclosed  herewith  you  will  find  our  complete  report 
ITo.  26727  covering  work  done  in  Key  West,  Florida,  between 
February’ 10th  and  27th  inclusive.  In  making  out  this  report 
t  have  endeavored  to  include  all  of  the  information  necessary 
In  interpreting  the  results.  If  we  can  be  of  any  service  in 
heitiins  to  interpret  the  results  or  compiling  other  data,  ple-se 
call  uron  us.  If  there  are  any  points  which  are  not  entirely 
clear,* I  should  be  very  glad  to  make  further  explanations. 

In  the  case  of  table  Ho.  8  where  the  relative  brightness 
of  the  white  plate  immersed  in  the  Gulf  Stream,  it  will  be  noted 
that  the  plate  could  be  seen  at  a  considerable  greater  depth  than 
•20  feet.  However,  the  small  waves  have  produced  so  much  refrac¬ 
tion  and  shifted  the  apparent  position  of  the  plate  so  : 
and  to  so  great  an  extent  that  it  was  not  possible  to  hold  the 
-ohotometor  field  on  the  plate  long  enough  to  secure  measurements. 
Further,  the  measurements  at  a  depth  of  15  to  20  feet  are  quite 
uncertain  for  the  same  reason.  When  the  plate  was  immersed  upon 
the  shady  side  of  the  submarine  chaser  the  sun

and  greater.

Purpose  of  Test 

The  purpose  of  the  test  was  to  determine  the  ranees  and 
order  of  magnitude  of  water  end  say  brightness  and  daylight 
illumination  under  different  conditions  of  shy  throughout  the  day. 

A  series  of  investigations  were  made  covering  different 
periods  of  eight  days.  In  order  to  determine  the  brightness  above 
the  horizon  the  3ky  'brightness  measurements  were  made  on  the 
meridian  and  on  the  arc  of  a  great  circle  passing  through  the  East, 
Zenith  and  West  at  altitudes  extending  from  the  horizon  to  the 
zenith  at  22-l/2  intervals.  As  the  cloudiness  in  the  direction  of 
observation  has  a  considerable  influence  on  the  degree  of  brightness, 
the  character  of  such  cloudiness  is  noted.  Daylight  illumination 
is  also  greatly  influenced  by  the  amount  and  character  of  the  clouds 
in  the  sky.  Therefore  v/ith  the  measurements, sky  and  cloud  conditions 
are  noted. 

Key  West  is  situated  at  Let.  24°  S3’  Horth.Long.  at  61°  48’ 
West  and  is  in  the  central  time  belt  using  the  90th  meridian  time. 
During  the  time  of  measurement  (February  18th  to  27th  inclusive) 


deport  U o . 26727 

the  equation  oi'  tiiae  varies  from  14  minutes  and.  £  seconds  to 
12  minutes  and  58  seconds;  therefore  the  local  apparent  time  for 
iCey  West  is  taken  as  19  minutes  later  then  SOth  meridian  standard 
time.  In  order  that  the  measurements  may  he  applicable  to  other 

locations,  the  time  in  all  cases  has  been  changed  to  local 

,  at  noon 

apparent  or  sun  time.  On  February  18th  the  sues  altitude/ was  u6  . 

•  It  v/as  hoped  that  measurements  might  be  obtained  on  a 

cloudless  day,  also  on  en  evenly  overcast  day,  in  order  that  data 
might  be  determined  for  the  two  extremes  and  the  values  interpolated 
for  sky  conditions  varying  between  these  extremes.  During  tne 
period  between  February  16th  and  27th- inclusive  there  v/as  no  day 
which  completely  filled  either  of  these  two  conditions  for  any 
extended  period  of  time.  The  weather  bureau  records  for  Jley  'v.'eet 
were  examined  and  it  was  found  that  but  two  evenly  overcast  days 
had  occurred  between  September  1st,  1917  ana  the  time  of  examination 
of  the  records,  February  22nd,  1918.  further  there  had  been  but  three 
or  four  days  during  this  period  when  the  sky  was  cloudless  for  any 
extended  period  during  the  day,  and  in  no  case  during  this  time  was 
the  early  morning  sky  entirely  cloudless.  On  iebruary  2brd  several 
times  during  the  morning  the  sky  was  entirely  cloudless,  but  this 
condition  lasted  for  only  a  few  minutes  at  a  time.  During  each 
of  the  other  days  the  clouds  were  present  in  the  sky  in  varying 
amounts,  nevertheless  measurements  were  made,  even  though  the 
conditions  were  far  from  ideal. 

In  order  to  secure  complete  information,  illumination 
measurements  were  taken  to  accompany  the  brightness  measurements. 

In  several  oeses  the  brightest  clouds  in  the  sky  were  measured  and 


Report  Ko . 26727  -3- 

founa  to  be  considerably  brighter  than  the  surrounding  blue  sky. 

In  all  cases  they  were  heavy  white  cumulus  clouds  so  located  that 
the  sun's  rays  fell  directly  upon  them,  increasing  their  brightness 
to  a  maximum. 

Under  all  conditions  the  blue  sky  was  found  to  be 
considerably  brighter  at  the  horizon  than  elsewhere,  with  the 
exception  of  that  part  of  the  sky  adjacent  to  the  sun. 

Eight  investigations  were  made,  the  results  of  which  are 
discussed  and  summarised  in  the  following  pages  and  tables. 
Investigation  H'o.l.  (fable  flo.l) 

On  February  18th  the  condition  ox  the  sky  was  not  ideal 
but  an  investigation  was  made  in  order  to  secure  values  which, while  not 
conclusive  or  indicative  of  the  range  of  brightness  under  clear  or 
overcast  sky,  might  nevertheless  be  of  value  for  interpolation.  The 
photometer  was  placed  on  the  southwestern  parapet  of  Fort  Taylor 
where  an  unobstructed  view  of  the  horizon  could  be  hcd  to  the  south 
and  west  with  a  sky  line  to  the  north  and  east  having  a  maximum 
altitude  of  3  degrees.  The  photometer  was  directed  toward  the  south 
just  above  the  horizon  and  measurements  made  from  this  position  up 
to  zenith  and  down  to  the  north  horizon  at  22-1/2  intervals.  The 
same  procedure  was  follov/ed  pointing  the  photometer  to  the  eaBt 
and  describing  the  3eme  arc  toward  the  west.  These  measurements 
were  continued  throughout  the  day  until  sunset.  The  observations 
taken  at  11:32  a. in. ,  showing  light  cumulus  clouds,  are  somewhat 
low  due  to  black  smoke  near  the  horizon  (from  the  city). 

Immediately  after  sunset (at  5:42)measurements  were  made 
of  sky  brightness  near  the  horizon, (H,  E,  S  and  W, )as  noted  at  the 

of  the  table.

Investigation  Ho.  2  (Table  Ho. 2) 

On  February  ISth  and  20th  a  study  was  made  of  the 
brightness  at  zenith  with  different  conditions  of  sky.  Most  of  the 
measurements  were  made  with  the  photometer  pointing  et  clear  blue 
sky  with  surrounding  clouds  in  varying  amounts.  Cloud  conditions 
and  their  positions  are  noted  throughout.  When  clear  blue  sky 
without  haze  is  observed,  the  brightness  is  apparently  independent 
of  the  kind,  amount  or  position  of  clouds  in  the  sky. 

(Table  Ho. a) 

On  February  20th,  measurement  was  made  of  horizontal 
illumination  from  the  moon.  The  moon  was  about  half  full 
(altitude  not  recorded).  Therefore  the.  intensity  shown  in  the  table 
of  approximately  half  the  published  value*  is  consistent. 
Investigation  Mo. 4  (Table  Mo. 4) 

On  February  21st  the  conditions  of  the  sky  were  slightly 
less  favorable  then  on  February  16th,  but  an  investigation  was 
carried  on  in  the  hope  that  the  data  obtained  might  prove  of  some 
value  for  interpolation  purposes.  The  measurements  were  made  on 
Sand  2ey  with  the  photometer  so  placed  as  to  give  an  unobstructed 
horizon  to  the  M,  S,  S  end  W.  The  only  buildings  on  the  island  were

the  lighthouse  aid  the  weather  bureau,  and  the  photometer  .  was 
pieced  at  a  sufficient  distance  so  that  little  or  no  light  was 
obstructed  by  the  buildings.  During  these  measurements  no  note 
was  made  of  the  amount  of  clouds  in  the  sky.  and  the  measurements 
were  discontinued  on  account  of  extreme  variability  of  the  sky. 
Investigation  Ko.5  (gable  Ho. 6) 

On  February  22nd  the  sky  was  covered  with  a  number  of 
small  shifting  clouds  throughout  the  entire  dey ,  therefore  no 
measurements  similar  to  investigations  1  and  3  were  made.  During 
the  latter  part  of  the  afternoon  measurements  of  water  and  sky 
brightness  were  taken  from  the  top  of  the  lighthouse.  She  water 
and  sky  were  viewed  at  corresponding  angles  from  the  horizon  with 
the  supposition  that  the  brightness  of  the  water  would  bear  a 
definite  relation  to  the  brightness  of  the  sky  at  the  corresponding 
angles.  These  data,  however,  ere  incomplete,  end  those  made  toward 
the  shallow  water  ere  not  applicable  to  deep  blue  water,  further 
the  water  was  so  far  from  the  base  of  the  lighthouse  that  it  could 
not  he  viewed  at  an  angle  greater  than  56  degrees  to  the  horizontal. 
Investigation  Ho. 6  (Table  Ho. 6) 

On  February  23rd  the  conditions  of  sky  were  good  throughout 
the  greater  part  of  the  morning  and  a  complete  set  of  data  were 
secured  from  6:25  in  the  morning  until  1:06  in  the  afternoon. 

During  these  measurements  complete  sky  conditions  weie  noted,  namely, 
(a)  the  condition  of  sky  and  kind  of  clouds,  if  any, in  the  direction 
of  observation,  (b)  the  amount  of  sky  covered  by  clouds  in  tenths, 

(o)  the  kind  of  clouds  in  the  entire  sky.  For  example,  the 
observations  at  6:25  a.m.  were  taken  at  2  degrees  altitude  (just 


Keport  Ho . 26727  -G_ 

tibove  the  north  horizon.)  The  clouds  in  this  direction  were  heavy 
white  cumulus  with  4/10  of  the  sky  covered  with  medium  and  dense 
cumulus  clouds.  The  brightness  under  these  conditions  was  101 

Investigation  Ho .7  (Table  Ho .7). 

On  February  26th  an  investigation  of  sky  end  water 
brightness  was  made  on  board  the  0.8.  Gunboat  Petrel.  The  photometer 
was" placed  in  the  after  port  life  boat  which  overhung  the  water  by 
10  to  15  feet.  During  the  measurements  to  the  East  and  South  the 
course  of  the  ship  was  Southwest,  and  during  the  measurements  West 
£nd  Horth  the  ship's  position  was  reversed  so  that  in  ell  cases 
an  unobstructed  horizon  was  secured.  However,  with  the  ship's  course 
northeast  some  of  the  brightness  measurements  of  the  water  end  the 
Illuminati on • measurements  with  the  photometer  test-plate  directed 
toward  the  water  are  probably  low,  resulting  from  the  fact  that  the 
Bhip  itself  threw  a  shadow  end  out  off  light  from  the  direction  of 
observation.  The  change  in  the  ratio  between  water  and  sky  brightness 
for  the  same  position  may  be  accounted  for  by  the  difference  in 
roughness  of  the  water.  During  the  measurements  the  ship  was  steeming 
forward  with  speed  only  sufficient  for  steerage  way.  The  observations 
were  made  in  the  deep  blue  water  of  the  Gulf  Stream. 

Investigation  Ho. 8  (Table  Ho.S) 

For  the  purpose  of  determining  the  reduction  of  brightness 
of  a  surface  immersed  in  water  at  different  depths,  an  iron  plate 
four  feet  square  was  painted  white  and  attached  to  four  ropes  so 
that  it  might  be  lowered  into  the  water.  The  coefficient  of  reflection 
of  the  plate  was  determined  while  dry.  and  found  to  be  43  per  cent. 


Keport  Mo. 26727  _7_ 

On  B’ebruery  26th  on  investigation  was  attempted  at  the 
Buoy  Dock  of  the  Kavy  Yard,  hut  the  water  was  not  sufficiently  clear 
to  render  the  results  of  any  value. 

On  February  27th  the  plate  end  photometric  apparatus  were 
ta,;en  aboard  a  submarine  chaser  and  the  study  made  in  the  clear 
blue  water  of  the  Gulf  Stream.  The  plate  could  be  readily  seen  at 
a  depth  greater  then  20  feet,  but  the  refraction  produced  by  the 
small  waves  shifted  the  apparent  position  of  the  plate  to  so  great 
an  extent  and  so  rapidly  that  photometer  readings  could  not  be 

taken  beyond  this  depth.

This  folder  contains  correspondence,  financial  documents,  and  technical 
notes  relating  to  research  on  various  projects  conducted  by  Edison  for  the 
U.S.  Navy  and  U.S.  Army  during  191 8.  The  bills  submitted  regularly  by  Edison 
show  that  his  main  project  for  the  Army  was  the  destruction  of  wire 
entanglements;  for  the  Navy,  submarine  detection  and  strategy  and  the 
phonograph  range  finder.  There  are  also  letters  to  and  from  the  Office  of  the 
Chief  Signal  Officer  dealing  with  experiments  in  field  communications.  A 
communication  from  Richard  W.  Kellow,  secretary  of  Thomas  A.  Edison, 
Personal,  indicates  that  the  billing  process  was  haphazard  due  to  secrecy 
concerns  and  the  rapidly  changing  nature  of  the  work.  At  the  end  of  the  folder 
is  a  list  of  experiments  from  March  1917  to  November  1918,  with  the 
laboratory  order  number,  description,  and  cost  of  each. 

Approximately  40  percent  of  the  documents  have  been  selected, 
including  all  of  the  substantive  correspondence,  a  small  number  of  technical

Dear  Sir: 

OUR  FILE  RW-54: 

Referring  to  our  conversation  in  Washington,  I 
am  enoloslng  sketch  of  a  shell  which  X  have  had  made,  show¬ 
ing  a  device  for  providing  that,  if  leakage  should  occur, 
the  leakage  will  lead  toward  the  outside  so  that  the  detonat¬ 
ing  part  of  the  shell  is  entirely  protected  from  the  contents 
of  the  she!  1.  The  soft  steel  ring  indicated  can  he  used,  or 
the  design  may  he  changed  so  as  to  give  a  wider  surface  of  con¬ 
tact  below  the  thread  so  that  an  asbestos  gasket  can  be  uBed. 

I  might  say  that  we  have  many  pipe  lines,  in  whioh  the  same 
material  is  oarried,  which  are  joined  by  means  of  flanged  pipe 
and  asbestos  paoklng,  whioh  practically  never  leak.  We  also  use 
many  thread  joints  wiped  with  red  lead  which  do  not  show  any 
signs  of  leakage,  so  I  believe  thiB  joint  can  be  made  perfectly 
tight.  Of  oourse  you  may  have  already  thought  of  an  arrange¬ 
ment  of  this  kind  and  I  am  sending  it  to  you  for  what  it  is 
wo rth. 

Yours  very  truly,

In  carrying  out  these,  experiments  I  havo  UBed  all 
tho  resources  of  my  laboratory,  including  tho  tub  machine 
shops  which  ferem  part  thereof,  Phis  experimental  work 
would  bo  much  facilitated  if  I  could  obtain  without  delay 
some  additional  equipment  in  the  lino  of  machinery,  but  in 
.shopping  around  to  purchase  some  the  best  promise  of  deliv¬

Dear  Sir: 

Xu  connection  with  our  experiments  at  Sandy  Hook,  it  appears  to  he 
neoossary  to  provide  the  commanding  officer.  Major  Kirk,  with  authority  to 
charge  certain  expenses  that  may  he  incurred  to  this  particular  work.  so 
far  no  expenses  havo  been  incurred  hy  the  Ordinance  Department  at  Sandy  Hoolc, 
hut  it  is  quite  likely  that  various  charges  will  havo  to  he  made  from  tlmo 
to  time,  and  it  is  difficult  for  them  at  the  present  time  to  know  how  to 
handle  them. 

j  I  Major  Kirk  states  that  when  they  have  had  experiments  to  do  for  the 

II  Havy  Department,  certain  appropriations  were  made  which  were  available  to  him 
l I  and  could  he  used  on  authorisation  of  the  Havy  representative  on  the  toot. 

11  Would  it  he  possible  to  have  Washington  assign  a  certain  credit  to  this  work, 

II  say  vSOO ,  which  would  be  used  on  such  jobs  that  would  have  our  approval,  so 
||  that  there  may  he  no  delay  due  to  possible  lack  of  authority  on  Major  Kirk's 
|  part  to  assist  us  at  any  time  in  our  work? 

V/e  are  arranging  with  the  Telephone  Company  to  install  the  polos  and 
will  do  most  of  the  work  ourselves  that  we  now  have  in  view,  but  there  are  cer¬ 
tain  incidental  expenses  that  the  Ordinance  Department  may  be  put  to  that  will 
have  to  be  taken  care  of. 

The  amount  stated  above  is  probably  in  excess  of  any  of  our  require¬ 
ments,  but  the  amount  of  credit  left  over  after  the  experiment  is  finished  con 
be  returned  to  the  general  fund.

Dour  Sir:-  ' 

She  following  experiments  wore  made  at 
Orango ,  15. J.,  to  determine  tho  feasibility  -of  main¬ 
taining  communication  over  field  wires  broken  by 
shell  fire. 

'  -  Swo  wires  each  600 -feot  long  wore  laid 

along  the  ground  parallel  -to  each  othor.  An  in  uc 
coil  or  a  single  widding  inductance  ooil*wei eased 
to  send  high  voltage  impulses  ovoi  one  ®  d 

throo  stage  audion  and  telephone  reeoivor. 
to  receive"  the  signals  induce a  in  tho  othor  wire. 




1.  Kith. both  wiros  unbroken  signals  could  bo 
hoard  with  tho  wires  276  feet  apart: 

~  7~ 

2.  liith  the  Bending  wire  broken  at  the  middle’ 
point  signal  could  be  detected  with  the  wires  100  feet  apart:. 

3.  With  the  wires  broken  as  shown  below,  signals 
were  detected  with  the  wires  5'  apart: 


By  holding  the  wires  up  every  60’  on  3  foot 
stakes,  little,  improvement  was  noticod: 

In  my  experiments  a  numbor  of  years  ago?  I 
vised  wiros  located  high  up  on  polos  and  much  bettor  results 
were  obtained.  It  appoars  that  the  proximity  of  tho 
wiros  to  the  earth  concentrates  the  electric  field  close 
to  the  wire  and  prevonts  its  effect  boing  felt  at  a  groat 
distance.  With  wot  grounds  or  in  rain  the  distance 
to  which  Bignalc  could  bo  sent  wero  somowhut  less  than 
notod  above. 

If  it  is  desirod,  I  will  continuo  the  experi¬ 
ments  and  try  to  improve,  upon  tho  rosultB  of  these  tostE  .

Signaling  by  means  of  Ground  Rod. 

1.  As  discussed  in  conference  with  Major  Charles 
A.  Culver,  24,  July,  it  does  not  appear  that  the  method 
of  signaling  in  discussion,  viz.,  that  of  signaling  by 
tapping  with  a  hammer  on  a  rod  driven  into  the  ground, 
presents  any  advantage  over  the  various  methods  of  sig¬ 
naling  at  present  employed,  such  as  secret  light  signal¬ 
ing,  etc. 

2.  It  is  also  thought  that  it  would  be  just  as 
easy  for  the  enemy  to  pick  up  the  signals  as  it  would 
be  for  our  own  force,  since  the  enemy  is  also  supplied 
with  suitable  amplifiers. 

3.  It  is  not  considered  practicable  to  develop 
this  method  of  signaling  at  the  present  time,  although 

it  will  be  kept  in  the  minds  of  the  Signal  Corps  engineers 
should  occasion  arise  in  which  it  could  be  used  to  ad¬

"It  is  believed  that  all  who  saw  these  two 
tests  agreed  that  they  were  the  most  remarkable  incen- 
diary  effects  ever  witnessed,  and  the  efficacy  of  the 
combination  of  the  Scheeleite  and  crude  oil  seems 
established  beyond  doubt." 

It  might  interest  you  to  know  that  after  trying  dozens  of 
materials,  it  was  Mr.  Silver's  suggestion  that  incorporated 
the  use  of  oil  and  paraffine  in  certain  quantities  vh  ich 
made  the  incendiary  material  controllable  as  to  time,  and 
produced  the  very  exceptional  result  which  is  described  in  tl 
above  quotation  from  Captain  Brinton,  and  also  stabilized 
the  material  against  danger  from  premature  ignition  by 
rifle  bullets.

Dear  Sir:- 

I  received  your  confidential  letter  of

coming  out  here  you  telephone  me  (Orange  907 )•  to  seo 
if  he  iB  available.  Ho  is.callod  away  from  the 
laboratory  occasionally  in  carrying  out7  his  experi¬ 
ments  for  the  Government;  > 

Hr.  Edison  also  wishes  me  to  say  that  ho 
suggested  to  tho  Command or  of  tho  Hydroplane  Corps 
the  us  o  of  a  double  wire  cord,  having  a ' lead  ball 
attached  six  feet  from  the 'bud,  to  be  carried  by  a 
hydroplane.  The  two  ends  of  wiro  coming  in  contact 
with  tho  salt  wator  would  closo  tho  .circuit  of  a 
vibrating  boll.  'fho  Hydroplane  Corps  desired  such 
an  indicator  to  toll  how  far  they  wore  above  tho  sea  . 
when  about  to  land,  as  it  dooms  difficult  to  Judge 
of  their  hights  from  the  wator.  At  the  time  this 
suggestion  was  offorod  by  Hr.  Edison,  two  hydroplanes

Mr.  \7m.  H.  Meadoworoft, 

Assistant  to  Mr.  Thos.  A.  Edison, 
Orange,  H.  J. 

Dear  Sir: 

I  have  received  your  letter  of  June  18th, 
and  will  try  and  arrange  an  appointment  hy  telephone, 
to  see  Mr.  Edison  Thursday  or  Friday. 

In  carrying  out  the  experiments  to  get  an 
accurate  gauge  on  the  height  of  the  hydroplane  above 
water,  I  have  found  it  impossible  in  practice  to  use 
a  V7ire  such  as  you  describe,  and  doubt  if  we  can  carry 
a  lead  ball  as  suggested.  We  have  tested  every  size 
of  wire  down  to  almost  hair  size,  and  find  that  the 
friction  of  the  water  make  the  wire  jump  ahead,  and  it 
tangles  itself.  There  is  a  constant  jerking  motion 
even  in  the  smoothest  water.  In  the  apparatus,  on 
which  I  am  working,  I  use  a  35  gauge  steel  drill  stem, 
and  could  of  course,  substitute  copper  or  brass.  This 
rod  also  jumps  on  the  water,  but  does  not  travel  for¬ 
ward  and  tangle . 

I  hope  to  get  Mr.  Edison's  suggestion  on 
some  ratchet  device  at  the  upper  end  of  the  rod,  or 
something  similar  to  the  ratchet  switch  on  an  electric 
bulb  which  will  alternately  make  and  break  a  circuit 
every  time  the  tip  of  the  rod  touches  the  water .  The 
action  of  even  this  light  steel  rod  is  very  violent  at 
a  speed  of  75  miles  an  hour  or  over. 

I  have  noted  your  comment  concerning  the  mixture 
of  liquid  air  with  oily  waste,  to  be  used  explosively. 
This  is  one  of  the  combinations  on  which  we  are  working, 
and  is,  I  believe,  the  one  found  most  satisfactory  in 
'  blasting  work.  We  are  also  using  charcoal  and  other 
mixtures  of  similar  nature. 

I  believe  it  would  be  a  very  excellent  idea  for

on  which  to  concentrate  experiments  at  Jones  Point.

Dep'V'of  JU8tioe, 

Subject:  Roport  of  Progress  in  the  JonoB  Point  Experimental 

laboratory  for  the  period  July  4  -  14,1918. 

Sorgoant  T.  A.  Bulifnnt  and  1.  E.  Ashim  of  the  Chemioal 
Corps  roportod  on  Wednesday,  July  10th,  and  have  already  render¬ 
ed  very  considerable  servioo  in  carrying  out  the  tests.  Their 
general  familiarity  with  tho  methods  and  requirements  of 
oxnerimonts  made  at  tho  Amorioan  University  Experiment  Station 
indicates  that  they  will  prove  valuable  assistants  in  tta  future 
developments  at  the  Jonos- Point  laboratory. 

Problem  1  -  Incendiary  Darts: 

for  tho  sake  of  definiteness,  it  haB  boon  deoided  to  reduce 
the  amount  of  inoondiary  material  in  the  dart  case  to  9  inches, 
und  work  on  delaying  tho  combustion  to  one  minute.  Ihe  roduotion 
in  the  amount  of  tho  charge  has  boon  made  aB  a  result  of  tho 
suggestion  found  in  Col.  Ragsdale's  lettor  of  June  28th.  It  is 
understood  that  stabili3ere  are  en  route,  so  that  actual  testB 
may  be  carried  out  shortly. 

It  is  our  impression  that  tho  darts,  when  dropped  from 
several  thousand  foot,  will  tend  to  crush  near  the  base  of  the 
light  papor  tube,  and  miss^in  tho  ignition  of  the  main  portion 
of  the  material.  Wo  have,  therefore,  made  up  for  tests  a  new 
model  in  tho  small  bombs,  v/hioh  wo  hope  will  bo  somewhat  more 
substantial  and  moro  positive  in  the  firoing  devioo. 

Problom  2  -  Experiments  with  liquid  Oxygen.: 

Lieutenant  Armstrong's  report  to  the  Chief  of  tho  Bureau 
of  Ordnance  of  tho  Navy  haB  been  read  with  a  great  doal  of  in¬ 
terest.  Tho  roport  covered  tests  of  "Helline"  and  Liquid  Oxygon 
made  on  July  1  at  Jonos  Point.  Thoro  is  ono  disappointing 
feature  however,  whioh  we  feel  justified  in  re-opening  for  diB- 
ouBBion,  and  that  conoerns  the  opinion  that  liquid  oxygon 
is  entiroly  out  of  the  question  ns  a  naval  explosive.  There 
seems  to  bo  some  misconception  in  Lieutenant  Armstrong's  lotter 
to  Mr.  Lovoring  undor  date  of  July  6th.,  whioh  wo  feol  should  be 
pointed  out:  . 

Grantod,  that  the  use  of  liquid  oxygen  as  a  naval  explosive  for 
dopth  ohargos  would  require  installation  of  a  unit  aboard  ship, 
the  Bpaoe  romiired  for  such  nmit,  tho  timo  element  for  produo-  .' 
tion,  and  tho  horse-power  nooessary,  and  the  difficulty  of  manuf 
faoturo,  is  considerably  ovor- estimate.* 


Here  are  the  facte:  Tho  spaoe  nooeosary  ^a'lnitontho  Claude 
system,  for- the  production  of  approx.  2.6  litres  per  ox  , 

linuid  oxygen  is  6  x  3  x  11';  the  time  element  for  production  ie 
not  more  than  15-30  minutee  after  starting  up;  a  twenty-fiye 
H.P.  motor  would  take  oaro  of  the  operation  of  such  a  plant. 

There  is  the  further  argument  that  an  installation  of  this 
sort  could  entirely  do  away  with  existihr  refrigeration  Plants, 
in  that  the  evaporating  air  could  ho  used  for  the  io®  “achines, 
and  general  refrigeration  aboard.  Under  these  conditions  the 
installation  would  answer  two  purposes,  and  furniBh  in  addition  to 
the  refrigeration,  the  beginning  of  an  extremely  powerful  explo¬ 

On  the  other  hand,  we  agree  that  considerable  work  must 
be  done  particularly  in  reference  to  the  doyelopment  of  containers, 
and  the  determination  of  the  safety  of  handling  of  the  material. 
With  regard  to  the  latter  point,  the  evidences  are  that  the 
manipulation  is  extremoly  simple,  with  few  precautions  “o°®ssary. 
There  is  the  further  advantage  that  in  itB  application  to  mines 
and  depth  charges,  which  might  fail  to  explode  at  tho  expected 
timo,  the  whole  charge  becomes  inocuous  after  a  lapse  of  an  hour 
or  bo. 

A  repetition  of  tests  made  on  July  1,  together  with  tests 
of  tho  stability  of  the  explosive  will  be  made  today. 

Problem  4  -  Wing  Hope  for  Aeroplanes 

Samples  of  the  wing  dope  appliod  to  Irish  linep,  °°ppor 
and  tin  platoB  are  being  submitted  to  Haval  Constructor  ••  C. 
Hunsacker,  of  tho  Bureau  of  Construction  and  Hepair.  Those 
samples  will  go  forward  today.  All  the  tests  have  been  applied 
with  reference  to  tho  •specifications  for  wing  dope j and  spar 
varnishes.  As  waB.  mentioned  in  the  last  report,  the  basis  of 
tho  dope  is  Gum  copal  in  othylmethylkotone .  We  have  decided  to 
give  an  additional  protootion  in  the  way  °*  £?®Ethvlk2tone 
giving  two-  coats  of  potassium  silicato  in 

The  dope  and  varnish  appear  to  answer  the  requirements  of  the 
specifications,  particularly  with  reference  to  rapid  drj ing. 

Ten  minutes  is  sufficient  for  complete  Betting. 

Problem  9  -  Hoxamethylene  in  Flares  and  Hockotsj. 

Hexamethylenetetramine  with  sodium  peroxide  gd-yoo.  as  we 
have  pointod  out  previously,  a  yellow  flame,  which  1b almost  1m 
possible  to  mask  in  any  way  with  salts,  so  that  we  could  expect 
very  little  in  the  way  of  development  of  rod,  white  and  Green 
flnros  with  this  mixture.  On  the  other  hand  hexamethylenete¬ 
tramine  nitrate  when  combined. with  Balts  offers  ^y  POBitive 
encouragement  along  this  lino,  and  possesses  some  very  inter 
esting  properties: 

1)  The  flame  is  high  candle  power,  and  burns  for  a  long 
lntorval  for  a  small  quantity  of  material. 


Z)  The  nitrate  roadily  takes  on  the  coloring  of  various 
volatile  salts. 

We  look  forward  to  the  solution  of  thiB  problem  in  uomoof 
the  salts  of  hexamothylonotetrnraine,  hut  at  the  present  we 
are  not  ready  to  give  anything  definite  in  the  way  of  a  report. 

Problem  6.  Hexamethylenetetramine  in  Explosive  mixtures:, 

following  up  the  observation  of  last  week,  that  hexamethyl¬ 
enetetramine  was  completely  detonated  inliquid  oxygen,  v/o 
oarried  out  a  test  in  a  steel  three-pounder  for  the  purpose 
of  determining  the  extort  of  detonation  of  the  material  alone , 
with  the  aid  of  a  booster.  The  detonator  and  footer wore  ■ 
encased  in  a  tube  3  l/4"  long,  which  could  be  inserted  in  the 
base  of  the  shell,  and  made  perfectly  tight.  With  a  Ho.  6 
detonator,  and  5  grams  of  THT,  we  were  able  to  detonate 
30  grams  of  hexamethylenetetramine,  moro  or  lesB  completely. 

The  steel  shell  was  fractured  in  a  number  of  pieoes.  A  repeti¬ 
tion  of  this  test  will  be  made  today. 

The  opportunity  for  the  continuation  of  tests  of  varying 
proportions  of  hoxn  and  sodium  peroxide  has  presented  itself,  and 
we  hope  to  be  able  to  decide  on  the  optimum  proportions  at  an 
early  date. 

The  preparations  of  and  explosive  tests  of  various  compounds 
of  hexamethylenetetramine  has  boon  continued,  and  will  be 
reported  on  shortly.

Hr.  Geo.  E.  Crawford,  suojeoL; 

Acting  Mayor.  VIA..  WAgRIOR_. 

Motile,  Ala. 

l£y  Bear  Mr.  Crawford 

Referring  to  inquiry  of  Mr.  Thomas  A.  Edison,  I 
am  informed  ty  the  Pratt  Consolidated  Coal  Company,  which 
bring  coal  both  by  water  and  by  rail  from  its  mines  ™e 
Birmingham  District,  that  all  large  contracts  < especially 
for  Government  purposes,  regular  delivery  could  be  assured. 

The  present  Government  price#  delivered  to  steamer 
at  Mobile  is  $7.00  per  ton  for  foreign  shipment  and  $5.65  per 
ton  for  coastwise  or  other  shipment. 

The  facilities  of  the  Pratt  Consolidated  Coal  Co., 
which  you  understand  is  only  one  of  the  coal  ““P?"1®®  °p®fa+i"s 
here,  are  such  that  delivery  of  cargo  coal  could  be  made  at  the 
rate  of  about  250  tons  per  hour.  Bunker  coal  delivery  by  collier 
while  steamer  is  loading  cargo  from  pier  ooul*  *®  p*a?adt£e 
the  rate  of  from  100  to  150  tons  per  hour,  according  to  the 
size  of  the  steamer  and  arrangements  of  bunker  space. 

Under  present  conditions  the  cost  of  coal  at  this 
point  would  be  irrespective  of  whether  ^^transportation  from 
the  mine  is  by  rail  or  by  water.  This  condition,  of  course, 
does  not  obtain  in  normal  times  when  delivery  by  water  is  very 
much  cheaper. 

i  There  were  shipped  through  Mobile,  not  including  the 
•  amount  that  either  came  here  for  domestic  use. °?,wa®  : ^^via 
steamers  either  as  cargo  or  bunker  coal,  about  63,4-00  tons  via. 
the  Warrior  River.  This  was  all  high  grade  steam  coal,  suit¬ 
able  for  bunker  purposes. 

- t-'i  As  you  are  already  obtaining  from  another  source  in¬ 
formation  as  to  the  facilities  of  the  Mobile  Coal  Company  and 
il-the 'Zimmera  Coal  Company,  I  will  not  attempt  to  cover  that 
matter  Jin  this  letter. 



It  is  of  interest  to  compare  chemical  analysis  and  calor¬ 
ific  value  of  Alabama  coalB  with  Pittsburgh  and  Virginia  coals; 
Edgewater  (Pratt)  is  unwashed  lump;  LipBey  and  Brookwood  coals 
are  washed  run  of  mine,  Pittsburgh  is  unwashed  run  of  mine,  as 
are  also  New  River  and  Pocahontas  coals:

I  am  enclosing  for  your  information  a  telegram  that  I  have 
just  sent  to  Mr.  Thos.  A.  Edison,  urging  that  he  come  to  Mobile 
for  a  personal  inspection,  and  stating  also  that  if  a  personal  trip 
is  impossible  we  would  welcome  the  opportunity  to  supply  him  with 
full  information  regarding  Mobile,  not  merely  from  the  standpoint 
of  fuel  but  also  from  many  other  standpoints,  with  especial  rela¬ 
tion  to  shipping  and  shipbuilding. 

Any  further  service  that  we  can  perform  in  this  matter,  the 
full  possibilities  of  which  are  unknown,  will,  I  assure  you,  be 
rendered  as  promptly  and-  efficiently  as  possible. 

Yours  very  sincerely.

The  Heason  ID  only  use  small  boats  from  60  to  200

whereas  there  seems  to  be  plenty  of  the  amaller  onau. 
England,  after  the  fishing  season  was  over,  in 
used^hese  boats, 50  to  75  tons, in  carrying  coal  across 
the  English  Channel  at  a  part  where  the  passage  was 
X65  miles  across.  They  ouooeeded  in  carrying  nearly 
8  million  tons  and  not  a  boat  was  lost.

the  availability  of  these  boats  for  a  return  cargo  to

Dear  Sir: 

I  have  yours  of  February  12th,  and  will  immediately 
proceed  to  obtain  the  information  that  you  desire. 

I  expect  to  confer  with  the  Mobile  Coal  Company  and 
the  Chamber  of  Commerce  in  regard  to  the  matters  that  you  men¬ 
tion,  and  possibly  they  will  write  you  direct,  as  X  may  find 
that  it  will  be  better  for  them  to  do  so  than  for  the  informa¬ 
tion  to  come  through  me.  I  shall,  however,  ask  that  all  this 
be  treated  as  confidential  by  them. 

Please  feel  free  to  call  on  me  at  any  time  for  any 
service  I  can  render,  because  it  is  a  pleasure  for  me  to  do  so. 

Yours  very  respectfully , 


February  15,1918. 

Mr.Thos.A. Edison, 

U.  S.  Naval  station. 

Key  West, Florida, 

Dear  Sir:- 

Mr. George  E.  Crawford,  Acting  Mayor  of 
Mobile,  has  asked  me  to  reply  to  your  letter 
under  date  of  February  12th. ,  In  which  you  out¬ 
line  a  plan  of  delivering  coal  to  Cuba  by  the 
use  of  small  sailing  vessels. 

I  am  sure  that  this  plan  cam  be  most  success¬ 
fully  carried  out. 

The  time  consumed  In  loading  coal  Into  one  of 
these  'small  vessels  would  not  be  more  than  two  or 
three  hours,  and  several  could  be  loaded  at  the 
same  time  when  necessary. 

High  grade  coal  In  amount  up  to  1,500  or  2,000 
tons  per  day  could  be  furnished. 

The  price  of  the  coal  trimmed  In  the  vessels 

would  be  the  price  as  fixed  by  the  fuel  admin¬ 
istrator,  with  freight, war  tax  and  handling  charge 
added,  which  at  the  present  time  totals  $6.10  per 
ton  of  2,000  pounds  f.o.b.and  trimmed  in  vessel. 

The  Mobile  Coal  Company  carries  in  stock  at 
Mobile  at  all  times  several  thousand  tons  of  coal, 
and  are  in  close  touch  with  the  mining  section. 

This  business,  if  entrusted  to  us,  would  re?- 
ceive  the  most  careful  attention  of  the  officers 
of  this  company,  who  are  greatly  interested  in 
your  plan,  which,  as  before  stated,  I  am  sure  will 

be  most  successful. 

The  Information-  in  the  last  paragraph  of  your 
letter  pertaining  to  return  cargo  of  sugar  and  mo¬ 
lasses  will  be  forwarded  to  you  by  Mr. Geo.E. Crawford, 
very  truly  yourj3,

Bear  Sin-  .  q-/*  ‘‘  ^  l'  j  ^  ' ., 

Replying  to  your  confidential  favor  of-  February  12tji^ 
addressed  to  Mr  Geo  E  Crawford,  Acting  Mayor  of  Mobile  ■-*  ^ 

Mr  Crawford  has  asked  me  to  answer  your  letter  for  they., 
reason  that  I  have  been  connected  with  the  handling  of  traffio  to 
and  from  Cuba  for  a  number  of  years.  . 

To  be  entirely  frank  with  you,  your  proposition  does  not 
appear  to  me  to  be  a  practical  one  from  a  commercial  standpoint.  , 
Your  idea,  however,  in  my  judgement,  is  entirely  feasible,  if  the 
profits  to  the  schooner  can  be  taken  oare  of  by  either  you  or  the 
Government,  as  suggested  in  your  letter. 

In  the  first  place.  Mobile  is  oonneoted  with  the  coal 
fields  of  Alabama  both  by  railroads  and  by  navigable  rivers.  The 
coal  deposits  in  the  Birmingham  district  are  unlimited,  and  the 
coal  is  of  excellent  quality  for  steam-making  purposes.  The  short 
railroad  line  Birmingham  to  Mobile  is  262  miles.  The  rail  freight 
rate  from  the  Birmingham  district  is  $1.00  per  ton  of  2,000  pounds. 
This  freight  rate  includes  the  ooBt  of  dumping  the  coal  into  ship’s 
hold  over  coal  tipples.  The  Southern  Railway  has  a  coal  tipple  at 
this  port  with  a  capacity  for  handling  seven  to  eight  hundred  tons 
per  day.  The  louisville  &  Hashville  Railroad  has  a  tipple  that 

-  2  - 

will  handle  about  1,500  tons  per  day,  if  the  tipple  is  worked  day 
and  night,  which  can  he  done.  The  rail  freight  rates  over  both 
lines  are  the  same. 

During  the  year  1917  there  was  handled  from  the  Birmingham 
dsitriot  about  80,000  tons  of  coal,  in  self-propelled  barges  from 
points  on  the  Warrior  River,  thence  via  the  Alabama  River  to  Mobile. 

The  80,000  tons  was  used  in  Mobile  for  ship  bunkering  purposes. 

Coal  can  be  transported  by  water  from  the  Birmingham  district  cheaper 
than  by  rail.  The  exact  cost  of  water  transportation  X  am  unable  to 
state,  but  I  should  say  not  exceeding  sixty  or  seventy  cents  per 
ton.  The  barge  lines,  for  reason  unknuwn  to  me,  have  for  the  present 
been  discontinued.  It  is  my  understanding,  however,  that  the  barges 
are  available,  and  can  be  put  back  into  operation  on  short 

The  most  serious  obstacle  to  your  scheme  is  finding  re¬ 
turn  loads  for  schooners  to  Mobile.  If  the  boats  have  to  return  light 
of  necessity  the  cost  of  ocean  transportation  would  be  practically 
doubled.  There  are,  however,  two  chances  for  return  cargoes  from 
Havana  and  other  Cuban  ports  for  schooners.  The  first,  and  most 
probable  return  cargo  would  be  blackstrap  molasses.  The  port  of 
Mobile  last  year  handled  about  75,000  tons  of  blackstrap,  princi¬ 
pally  from  Cuba.  This  blackstrap  1«  handled  to  us  in  tank  ships, 
and  pumped  into  storage  tanks  at  Mob i 16.  These  cargoes  are  brought 
to  us  in  ships  that  bring  about  8.000  tons.  The  storage  tanks  at  Mobile 
will  hold  about  85,000  tons.  A  ship  with  8,000  tons  can  be  discharged 
from  ship  tp  tank  within  ten  or  twelve  hours.  The  blackstrap  is 
moved  from  tanks  into  tank  oars  by  a  pumping  process,  which  is  a 
very  economical  way  of  handling  it.  It  is  estimated  that  the 
oost  of  transportation,  even  at  the  present  high  price  of  ships, 

from  Havana  to  Mobile,  on  blackstrap,  is  12^  per  100  pounds.  This 
oost  includes  the  expense  of  returning  the  ship  from  Mobile  to 
Cuban  ports  light. 

The  other  possible  commodity  to  move  from  Cuba  to  Mobile; 
is  asphaltum.  There  is  quite  a  valuable  deposit  of  asphalt  at  Mariel 
Bay,  40  miles  west  of  Havana.  It  is  owned  by  British  oapital.  The 
International  Asphalt  Company,  of  Chicago,  at  one  time  controlled 
the  Mariel  deposit,  and  imported  through  Mobile  some  twenty-five 
or  thirty  thousand  tons  per  year,  refining  the  asphalt  at  this  port. 
About  three  years  ago,  however,  the  refinery  here  was  shut  down 
on  aocount  of  some  legal  complications  between  the  International 
Asphalt  Company  and  the  owners  under  the  contract  existing  between 
them.  It  is  my  understanding,  however,  from  recent  information, 
that  the  refinery  here  could  be  re-opened  but  for  the  extreme  high 
ooean  freight  rates  now  existing.  Based  on  the  information  contained 
in  your  letter,  I  have  this  morning  wired  the  International  Asphalt 
Company,  asking  if  they  could  re-open  their  plant  here  if  a 
reasonable  ocean  freight  rate  was  obtainable.  I  will  advise  you  of 
the  nature  of  their  reply. 

Referring  again  to  the  question  of  blackstrap:  The  dif¬ 
ficulty  in  handling  this  commodity  in  soho oners, as  I  see  it,  would 
be  the  question  of  returning  the  empty  barrels.  All  of  the  sohoonerB 
Bpaoe  under  deck  would  be  taken  up  with  coal  on  return  tripB,  and 
barrels  could  not  be  loaded  safely  on  deck  of  a  Bmall  schooner. 

notwithstanding  what  I  have  stated  about  the  blackstrap 
proposition,  there  was  handled  to  this  port  from  Sagua  la  Grande, 
'Cuba,  on  July  6th,  1917,  997  barrels  of  blackstrap,  aggregating 
329  short  tons,  in  the  Schooner  DAVEHPORT.  This  blackstrap  waB 

-  4  - 

distributed  in  barrels  by  rail  to  interior  points’.  We  nov;  have  at 
our  docks  the  Schooner  CHAMBERLAIN,  from  Manzanillo,  Cuba,  with 
1,200  barrels  of  blaokBtrap,  or  396  short  tons,  five  hundred 
barrels  of  this  lot  will  be  distributed  to  the  interior  in  barrels. 
The  remaining  700  barrels  are  now  being  pumped  into  the  storage  tanks 
at  Mobile.  This  pumping  process  from  barrels  is  an  experiment, 
and  if  successful  will  largely  Bolve  the  question  of  return  cargoes. 

I  am  confidentially  informed  that  the  movement  of  black¬ 
strap  through  the  port  of  Mobile  for  the  coming  year  will  probably 
aggregate  150,000  to  175,000  tons.  I  furthermore  know  that  tank 
ships  are  as  scarce  as  other  kinds  of  ships,  and  am  therefore 
inclined  to  believe  that  a  contract  can  be  made  for  return  cargoes 
of  blackstrap,  if  the  pumping  process  from  barrels  to  tanks  is  a 
success.  I  have  gone  into  the  details  of  this  question  of  return 
cargoes  rather  fully,  as  on  this  one  feature  rests  the  question 
of  carrying  out  your  idea  to  a  suooessful  business  conclusion. 

For  your  information  I  will  advise  that  Mobile  is  the 
largest  port  of  export  in  the  United  States  for  yellow  pine  lumber. 
Suoh  being  the  case,  lumber  oargoes  are  always  available,  and  all 
sailing  oraft  are  now  very  much  in  demand  for  the  lifting  of  yellow 
pine  lumber.  The  present  lumber  rate  by  schooner  from  Mobile  to 
north  side  Cuban  ports  is  about  $20.00  per  thousand  feet,  which 
would  be  equivalent  to  $10.00  per  ton.  I  mention  this  feature,  as 
the  rate  on  lumber  would  have  a  very  material  bearing  on  your  rate 
on  coal  by  sohooner.  The  schooner  rate  quoted,  however,  is  based  on

however,  the  sailing  boats  are  returning  to  us  with  oargoeB  of  mahog¬ 
any  from  Mexico,  and  logwood  from  certain  of  the  islands  of  the

West  indies  other  than  Cuba,  such  as  Haiti  and  Santo  Domingo.  If 
cargoes,  however,  could  he  assured  to  schooners  both  ways,  the  cost 
of  transportation  on  coal  hy  water  could  he  materially  reduced  under 
the  present  quotations. 

In  your  letter  you  make  reference  to  a  reliable  dealer 
who  could  promptly  load  and  handle  your  schooners.  In  this 
connection  I  would  suggest  the  firm  of  las  Gibboney  &  Company, 
jas  Gibboney  &  Company  are  ship  brokers,  and  were  for  a  number  of 
years  agents  for  the  Munson  Steamship  line,  which  company,  for  the 
last  seventeen  years,  has  maintained  a  regular  steamship  service 
between  Mobile  and  ports  in  Cuba,  as  indicated  on  the  sailing  card 
I  attach  hereto,  fheir  former  connection  with  the  Munson  line 
makes  them  thoroughly  familiar  with  all  of  the  intricacies  of  handling 
Oobian  traffic, ‘both  to  and  from  the  island.  In  addition  to  the  ex¬ 
perience  that  thev, have  had  with  the  Mnnson  line,  they  have  been  in 
the  coal  handling  huBinesB  for  the  last  fifteen  years,  at  times 
handling  export  coal,  hut  more  particularly  supplying  steamships 
at  Mobile  with  hunker  coal. 

If  you  should  desire  additional  information,  or  think  that 
I  can  be  of  service  to  you  in  any  way,  I  am  at  your  command.  In 
making  this  offer  I  want  to  assure  you  that  it  is  purely  on  a 
patriotic  basis.  I  am  too  old  to  Moulder  a  gun,  which  I  regret. 

I  have  just  passed  my  fifty-seventh  birthday,  but  am  strong  and 
vigorous,  and  more  than  anxious  to  serve  my  country  in  any  way 
possible.  I  make  this  statement  to  you  feeling  that  the  same  sen¬ 
timents  prompt  you  to  relieve  the  coal  situation  in  Cuba. 

I  consider  it  an  honor,  and  therefore  a  pleasure,  to 
be  able  to  address  you  this  letter.

Mr.  A.  0.  Danner,

Mobile,  Ala. 

My  dear  Sir: 

Your  letter  of  February  18th  to  Mr.  Edison  is  at  hand. 

Your  suggestion  in  regard  to  shipping  ooal  directly  from  the 
mines  to  Cuba  by  the  Florida  East  Coast  Railway  is  appreoiated, 
but  the  oapaoity  of  the  road  seems  to  be  taxed  to  its  limit 
at  present  in  the  transportation  of  food  stuffs  and  supplies 
and  the  plan  proposed  by  Mr.  Edison  was  particularly  to  relieve 
the  other  means  and  lines  of  transportation  so  that  it  would 
not  in  any  way  interfere  with  these  already  overorowded  routes, 
and  furthermore  to  enable  the  owners  of  sailing  vessels  to  use 
them  to  advantage  and  profit. 

Mr.  Edison  has  not  the  time  or  desire  to  enter  into  the 
ooal  and  sugar  business  personally  beyond  a  demonstration  trip 
tSitow  thafit  oan  be  done  and  with  profit,  and  to  encourage 
others  to  engage  in  the  trade.  He  has  no  desire  to  make  any 
money  out  of  it  personally.  He  has  even  made  offers  to  s®™™1 
ship  owners  here  to  guarantee  all  expenses  and  a  pr°iit  of  two 
dollars  ner  ton  and  on  top  of  that  give  them  all  the  trip  brings 
inprolitabove  “at  amount,  in  order  to  make  a  demonstration 
trip.  The  trouble  seems  to  be  that  the  owners  of  s^lP®h®^® 
either  have  other  oontraots  or  charters  or  oannot  ®®°ur®  £®*P 
to  man  their  boats.  They  say  orews  are  not  to  be  had,  although 
they  are  offering  $60  per  month  eaoh  for  them. 

The  above  being  the  ease  you  can  understand  J^t  Mr.  Edison 
would  not  be  interested  in  any  boats  for  sale  as  he  has  no 
intention  of  engaging  in  the  trade  personally  for  profit. 

lie  is  also  investigating  the  matter  of  getting  return  cargoes 
for  a  lot  of  boats  that  oarry  lumber  to  Cuba  and  return, light 
beoausethey  can  get  nothing  to  bring  back,  when  every  boat  that 

Mr.  A.  C.  Danner — Feb.  23,  1918. 

oan  should  bring  back  raw  sugar  or  molasseB  and  make  full  use 
of  the  energy  lost  by  returning  light. 

Your  suggestion  in  regard  to  the  use  of  tugs  is  a  good 
one  and  there  are  tug  and  ship  owners  who  have  of  both  that 
ought  to  be  interested  and  should  get  busy  on  this  trade  from 
a  purely  business  standpoint.  There  is  unquestionably  a  good 
profit  in  it. 

Very  truly  yours,

Near  Sir:- 

Referring  to  our  recent  correspondence  I  found  on 
inquiry  that  Mr.  J.  S.  Taylor,  Foreign  Freight  Agent  Mobile 
&  Ohio  &  Southern  Railway,  was  furnishing  the  desired  infor¬ 
mation  in  great  detail,  and  therefore  I  shall  not  attempt  to 
go  further  into  mattersso  far  covered  by  him. 

However,  in  pursuing  the  question  of  return  cargoes 
of  molaoseB,  concerning  which  I  wrote  tne  C.  U-  Synder  Company, 
it  appears  that  the  Sugar  Products  Company,  69  Wall  Street, 

New  York  City,  very  likely  will  be  interested,  although  tne 
Cuba  Distilling  Company  of  40  Exchange  Place,  New  York,  is 
using  tank  steamers  and  probably  would  not  be  interested  in  ■ 
the  small  sailing  draft. 

A  representative  of  the  Sugar  Products  Company  hap¬ 
pened  to  be  in  Mobile  at  the  time  my  inquiry  was  received  by 
the  C.  U.  Snyder  Company,  and  he  expressed  considerable  in¬ 
terest,  promising  to  take  the  matter  up  with  his  home  office 
at  once.  Unless  by  reason  of  their  close  relations  with  Mr. 
n’avlor  these  people  have  no  knowledge  of  the  source  of  ibis 
investigation  and  will  probably  reply  to  me.  In  that  event  I 
shall  of  course  transmit  the  information  at  once  to  you* 

Your  letter  to  Acting  Mayor  Crawford  was  marked  con¬ 
fidential  and  I  have  not  felt  at  liberty  to  use  your  name  in 
any  of  my  own  investigations,  which  include 

the  railroadB  and  other  concerns  looking  to  the  possible  devel

is  any  reason  for  the  view  taken  by  Mr.  Turner.  I  am  endeavor¬ 
ing  to  get  owners  of  sailing  vessels  and  barges  interested  in 
this  trade  and  have  gone  upon  the  assumption  that  there  would 
be  no  difficulty  in  getting  ooal,  as  per  your  letter  of  the

Mobile,  Alabama 

February  21,  1918. 

Mr.  Thomas  A.  Edison, 

Key  West,  Fla. 
My  dear  Sir: 

-sAddison  E.  Bullard:- 

I  beg  to  acknowledge  reoeipt  of  your  confidential 
letter  of  February  18th,  inviting  ship  owners  to  engage  in  the 
ooal  trade  to  Cuba. 

.  I  will  take  the  liberty  of  making  oertain  suggestions, 
in  regard  to  this  trade,  feeling  sure  that  you  want  all  th9  inform¬ 
ation  possible  upon  the  subject.  Being  a  Mobllian,  and  intensely 
interested  in  this  very  ooal  problem,  I  want  to  assist  in  any  way 
I  can. 

1.  There  is  no  ooal  supply  available  at  Mobile  for 

the  ships,  even  should  owners  deBire  to  engage  their  ships  in  ooal 
trade  to  Cuba. 

2.  There  will  be  no  ooal  supply  within  the  next  twelve 
months,  at  least,  unless  the  Government  steps  in  and  assists  in 
solving  the  transportation  difficulties,  viz.,  provides  suitable 
barges  and  towboats  to  barge  ooal  from  Alabama  mines  to  Mobile. 

The  railroads  have  been  unable  to  furnish  ooal  oarB  and  engines 
to  move  all  tho  ooal  necessary  for  domestio  and  bunker  purposes 
at  Gulf  ports. 

3.  It  would  be  perfeotly  useless  for  ships  to  come  to 
Mobile  to  get  ooal,  until  some  agenoy  first  arranges  to  con¬ 
centrate  ooal  at  Mobile  and  then  to  sell  same  to  Cuba.  This 
agenoy  is  usually  the  large  mine  operators,  operating  through 
selling  agents  at  the  ports,  or  Bunkering  Agents  at  tho  port,  who 
buy  ooal  from  the  mines  and  sell  the  ooal  0.  I.  F.  to  Cuba.  In 
other  words,  buy  the  ooal,  charter  the  shipB,  insure  the  oargo, 
and  make  the  delivered  prioe  to  oonsumers  in  Cuba. 

The  mines  cannot,  today,  ship  sufficient  ooal, 
due  to  shortage  of  oars,  engines,  and  orews,  to  supply  the  dom¬ 
estio  and  bunker  demand.  The  Bunkering  Agents,  therefore,  oannot 
get  sufficient  ooal  to  supply  the  looal  demand,  muoh  less  the 
foreign  demand.  Aooordingly  a  new  Bouroe  of  supply  must  be  found 
to  satisfy  the  neoessary  Cuban  demands.  This  supply  oan  beBt 
be  obtained  by  the  ubs  of  joint  rail  and  water  route  to  Mobile. 

The  ooal  oan  be  switched,  in  oars,  from  mines  near  the  River  to 
the  existing  ooal  handling  facilities  upon  the  river,  there  the 
oars  oan  be  discharged  upon  barges,  and  towed  to  Mobile.  There 
are  some  barges  now  available,  others  oan  be  brought  from  other 
points,  and  the  remainder  must  be  oonstruoted,  and  of  wood  inasmuoh 
as  steel  construction  is  not  readily  obtained  at  thiB  time.  ThiB 


will  require  hundreds  of  thousands  of  dollars,  and  the  Govern¬ 
ment  alone  oan  afford  this  large  investment  at  this  time. 

Coal  oan  he  produced  in  unlimited  quantities  at 
mines  upon  and  near  the  river.  The  present  oar  equipment,  v/hen 
used  only  in  the  short  switch  movement  between  the  mines  and  the 
Elver,  oan  transport  a  great  quantity  of  ooal.  The  problem 
then  is  barges  to  move  the  ooal  to  Mobile,  maohinery  to  unload 
barges  at  concentration  depots  at  Mobile,  and  the  same  maohinery 
to  aooomplish  the  rapid  loading  aboard  ships,  or  to  harbor  barges 
if  the  bunker  coal  is  to  be  taken  aboard  by  the  ship  while  she  is 
loading  her  oargo  at  the  wharf. 

The  Bunkering  Agencies  will  buy  the  coal  from  the 
mines,  sell  the  ooal  to  Cuba,  and  charter  the  ships  to  transport 
ooal  from  Mobile  to  Ouba,  onoe  there  is  a  eupply  obtainable.  The 
transportation  between  the  minos  and  Mobile  presents  the  real 
existing  difficulty.  This  transportation  is  the  vital  link  in 
the  chain,  and  to  supply  this  link  will  mean  a  large  sum  of  money. 
And  little  relief  oan  be  expected  for  Ouba  until  this  transporta¬ 
tion  is  furnished. 

4.  Mr.  A.  J.  Mason  and  Mr.  David  Bonteoou,  of  the  United 
States  Shipping  Board,  are  now  investigating  this  very  barge 
problem,  and  were  in  Mobile  on  Monday  and  Tuesday  of  this  week. 
Their  reoommendations  will  no  doubt  be  of  oonsiderable  assistance 
to  you  in  your  efforts. 

If  there  is  anything  that  I  might  do  at  this  end,  in 
the  way  of  furnishing  information,  eto. ,  to  assist  you,  kindly 
let  me  know.

Mr.  W.  M.  Clemens,

Bear  Sir: 

Your  letter  of  February  25th  to  Mr.  Edison  has  been 
received  and  the  contents  are  noted  with  interest. 

Mr.  Taylor  haB  been  very  kind  and  helpful  in  the  matter. 
It  is  probable  that  the  United  States  Shipping  Board  will 
take  up  this  whole  matter  and  that  some  good  solution  of 
the  problem  will  soon  be  found.  Some  ship  owners,  we  are 
informed,  have  begun  to  act  and  the  Munson  Line  are  now 
filling  their  spare  oargo  space  with  ooal,  so  that  the  fuel 
is  beginning  to  move,  and  with  the  assistance  of  the  Shipping 
Board  and  the  Food  Authorities  we  hope  that  Cuba  will  soon 
be  getting  a  good  supply  of  ooal  and  the  United  States 
getting  their  raw  BUgar  and  molasses  in  return. 

We  shall  be  very  glad  to  have  the  report  from  the 
C.  U.  Snyder  Company  when  it  oomes. 

Very  truly  yours. 

For  Mr.  Edison. 

Mr . Thos . A.  Edison . 

U.S. Naval  Station, 

Key  y;est,Fla. , 

Dear  Slr:- 

For  your  information,  in  reference  to  the  mat¬ 
ter  of  transporting  coal  from  Mobile  to  Havana,  Cuoa, 
the  Munson  Line,  running  steamers  from  here,  weekly, 
to  Cuba,  have  put  into  effect  a  rate  on  coal  from 
Mobile  to  Havana,  of  §7.93  per  ton  of  2£40  pounds; 
requiring,  however,  that  the  coal  we  sacked. 

The  adding  of  the  sacking  charge,  at  the  very 
high  cofet  of  sacks  now,  would  make  the  price  about  $4.00 
per  ton  more,  and  cause  the  shipping  of  coal  by  this 
line  prohibitive. 

Another  item  which  may  be  of  interest  to  you  is 
that  the  committee  from  Washington  which  I  mentioned  to 
you  in  one  of  my  letters,  has  reported  very  favorably 
and  strongly  recommending  putting  in  effect  at  once  the 
plan  of  bringing  coal  down  the  Warrior  River — a  new 

source  of  supply. 

They  recommend  that  the  shipping  hoard  use 
two  millions  of  dollars  for  this  work  Immediately 
and  that  they  establish  the  management  at  Mobile  and 
provide  here  a  large  storage  place  for  the  accumulation 
of  coal  for  supplying  other  ports  In  the  gulf,  hut  that 
does  not  provide  for  the  ocean  transportation,  which 
Is  the  serious  problem  just  now,  and  the  one  that  you 
have  discovered  and  have  been  trying  to  remedy. 

Yours  very  truly, 





March  7,  1910. 

Charles  B.  Hanford,  Esquire, 

United  States  Naval  Station, 
Key  West,  Florida. 

My  dear  Mr.  Hanford: 

Please  pardon  me  for  not  having 
answered  your  letter  of  February  21,  1918,  written 
hy  request  for  Mr.  Thomas  A.  Edison,  which  is  due  to 
the  fact  that  I  have  been  absent  from  the  City  for 
several  days  and  the  time  that  it  has  required  to  make 
a  close  study  of  the  proposition  of  importing  Alabama 
coal  into  Cuba  by  means  of  the  Cuban  vessels. 

There  are  a  number  of  steamers  and  sailing 
vessels  which  would  be  available  for  this  trade;  a  list 
of  which  I  send  you,  herewith  enclosed,  on  a  separate 
sheet,  and  while  the  national  Council  of  Defense  have 
assured  me  that  these  boats  could  be  placed  in  this 
traffic,  I  am  inclined  to  doubt  if  this  could  be  done, 
as  most  of  them  at  the  present  time  are  engaged  in 
carrying  sugar  to  Mexico.  Sometime  ago  the  Shipping 
Board  of  the  United  States  suggested  that  these  boats 
be  used  for  the  purpose  of  carrying  sugar  to  the 
United  States,  but  the  reply  was  that  they  were  required 
for  the  coast  wise  trade. 

We  are,  at  the  present  tine,  receiving  coal 
in  such  quantities  from  the  northern  ports  as  to  supply 
the  demand  for  the  Island,  end  the  condition  which 
existed  at  the  time  you  wrote  your  letter  does  not 
exist  now.  I  took  up  the  matter  of  the  importation

Mr . Chas . B.  Hanford , 
for  Mr. Edison, 

U.  S.  Naval  Station, 
Key  V/est  ,Fla. , 

Dear  Sir:- 

Your  favor  of  the  4th. Inst. came  duly  to  hand, 
hut  I  was  out  of  the  city,  which  has  caused  this  de¬ 
lay  In  acknowledging  your  letter. 

I  note  that  through  Mr.Edlson's  Influence 
that  there  may  he  a  party  sent  down  this  way  to  ex¬ 
amine  conditions  as  to  coal. 

If  this  man  comes  here,  and  Is  sent  to  me,  I 
will  he  glad  to  assist  him  in  getting  Information. 

In  the  meantime,  I  can  assure  Mr. Edison  now 
that  there  is  plenty  of  coal  here  and  no  difficulty 
In  getting  large  amounts. 

Vie  can  get  coal  from  Alabama,  and  we  can  also 
get  It  from  Illinois,  If  necessary. 

I  would  like  to  suggest  what  is,  In  my  opin¬ 
ion,  the  best  and  most  practicable  way  of  getting 
this  coal  to  Havana,  or  other  Cuban  ports,  as  far 
as  the  ocean  transportation  is  concerned; 

(I  will  say  that  I  have  been  handling  coal  here 
on  the  waters  more  or  less  for  the  past  forty  years; 
and  I  have  had  a  long  experience  with  It .trying  many 
different  ways) . 

There  should  be  for  the  proper  handling  of  this 
business  four  large,  strong,  sea-going  barges  con¬ 

Each  of  these  barges  should  have  a  carrying  ca¬ 
pacity  of  E, 000  tons. 

A  powerful  sea-going  tug  should  be  procured. 

The  plant  would  then  consist  of  this  tug  and 
four  barges. 

Two  of  the  barges  should  be  at  Havana. 

Two  of  them  at  Mobile. 

It  should  be  arranged  that  the  tug  would  leave 
Mobile  with  the  two  barges  here,  these  barges  loaded 
with  coal  (4,000  tons)  and  go  directly  to  Havana. 

The  tug  should  then  return  at  once  to  Mobile 
with  the  Havana  barges  loaded  with  sugar  or  any  other 
kind  of  goods  to  come  this  way. 

Of  course,  there  should  be  proper  facilities  for 
unloading  and  loading  with  dispatch  and  economy. 

This  plant  would  put  into  Havana,  say,  4,000  tons 
of  coal  per  week,  which  would  probably  be  all  that 
would  be  required. 

This  would  not  only  be  the  safest  and  most  expe¬ 
ditious  plan,  but  would  be  the  cheapest  way  to  handle, 
this  business. 

I  would  say  further  for  Mr. Edison's  Information 
(he  may  not  have  heard  of  it)  that  the  reason  Cuba 
has  gotten  into  this  fix  about  coal  Is  that  previous 
to  the  war  the  Philadelphia  sugar  refinery  concern 
(a  very  large  and  strong  company)  ran  from  Philadelphia 

+n  Havana  steamers  especially  built  and  constructed 
for  tKs"  They  carried  coal  to  Havana  and 
cnrar  pack-  and  they  did  not  permit  anyone  to  inter- 
fer^ with  their  trade.  They  had,  practically,  the 
monopoly  of  it. 

We  tried  years  ago  to  do  something  in  the  way 
of  sending  coal  to  Havana,  hut  we  could  not  compete 
with  the  Philadelphia  people. 

The  Louisville  &  nashvllle  R.R.Co.also  tried 
to  ship  coal  into  Havana,  and  lost  more  than  ^00,000.00 
before  they  gave  it  up. 

Now  .when  this  war  broke  out  and  the  price  of  steam¬ 
ers  went ’up  sky-high,  the  Philadelphia  people  sold  their 
steamers, and  Cuba  was  without  any  way  to  secure  coal. 

yours  truly.

"Why  cannot  your  Line  carry  deck  loads  of  coal  in  bags  from 
Mobile  to  Havana  price  about  six  dollars  Mobile  readily  sells  at  Havana 
Seventeen  Dollars  this  gives  you  a  good  freight  earning. 

received  and  delay  in  answering  same  has  been  caused  by  awaiting  develop¬ 
ments  at  Mobile.  We  wish  to  state  that  we  do  have  and  have  had  for 
some  time  a  rate  in  effect  of  *7.93  P«»r  ton  of  2240  pounds  on  coal  in 
bags  from  Mobile  to  Havana,  including  the  handling  charges  to  the  trucks. 
This  rate  is  even  lower  than  the  bulk  rate  from  Newport  News  but  the  cost 
of  bagging  and  the  difficulties  in  bagging  in  time  for  making  shipments 
without  great  expense  seems  to  stahd  in  the  way.  Furthermore  the 
quality  of  coal  is  a  thing  that  is  very  important. 

We  stand  ready  to  carry  any  of  this  business  that  can  be 
developed,  to  the  limit  of  the  capacity  of  our  ships,  whether  on  .dock 
or  under  deck;  first,  of  course,  taking  care  of  the  food  supplies  which 

are  taking  from  Mobile.

My  dear  Sir: 

Your  letter  of  the  7th  inat.  to  Mr.  Thomas  A.  Edison 
in  nt  h " nd  aid  1  thank  you  for  the  information  contained 
therein!  Ur.  Edison  has  been  very  much  interested  in  the  matter 
of  getting  o  supply  of  ooal  to  Cuba  and  also  in  procuring 
return  cargoos  of  raw  3Ugar  and  molasoos  to  the  United  States. 

There  are,  ov  have  been,  many  vessels  ourrying  lumber 
and  other  oommoditiea  to  Cuba  whioh  return  to  the  United 
States  light,  and  a  number  have  appealed  for  help  in  getting 
return  oargoes  to  avoid  thia  great  waste  of  energy.  We  have 
taken  the  liberty  of  referring  them  to  you  and  if  you  can 
give  thorn  any  assistance  in  procuring  return  oargoes  it  will 
he  greatly  approoiated.  Mr.  Edison  has  no  personal  or 
monetary  interest  in  the  matter  and  has  acted  only  for  the 
good  of  the  oauae.  .

that  Ur.  Edison  has  succeeded  in  interesting  the  United 
States  Government  officials  in  the  matter  and  further  details 
should  te  taken  up  with  thorn. 

It  i3  suggested  that  all  matters  In  regard  to  the  avail¬ 
ability  of  ships  should  be  taken  up  with  Honorable  Edward  H, 
Hurley',  Chairman  of  the  United  States  Shipping  Board, 
Washington,  D.  0. 

Ihe  matter  of  proouriag  return  cargoes  of  raw  sugar  and

Mr.  Edison's  sole  purpose  and  interest  in  the  matter  has 
been  to  gst  shin  ownerB  interested  and  get  this  trade  started. 
In  this  he  has  been  successful  to  some  extent  and  his  efforts 
have  been  made  without  selfish  or  monetary  interest  personally, 
but  simoly  for  the  good  of  the  cause.  The  matter  is  now  in

Dear  Sir: 

Your  letter  of  March  13th  to  me  for  Ur.  liaison  is  at 
hand.  I  enclose  herewith  a  oopy  of  a  general  letter  sent  out 
to  all  those  who  have  responded  or  shown  an  interest  in  the  ooal 
proposition,  which  will  explain  the  present  status  of  affairs 
and  also  the  fact  that  you  are  prepared  to  furnish  ooal  at 
the  rates  we  have  quoted  to  them. 

By  direotion  of  Mr.  Edison  I  am  sending  a  letter  to-day  to 
Mr.  W.  M.  Clemens,  General  Secretary  of  the  Mobile  Chamber  of 
Commerce,  telling  him  that  there  has  been  almost  universal 
oomplaint  about  the  quality  of  Alabama  ooal  and  suggesting  that 
the  Chamber  of  Commerce  should  take  steps  to  correct  the 
impression  which  has  unfortunately  been  brought  about  by  some 
means  and  which  if  allowed  to  stand  would  do  much  to  injure 
Mobile  as  a  ooal-pur chasing  market.  I  have  no  doubt  that  as 
your  first  letter  to  Mr.  Edison  was  written  at  the  suggestion 
of  Acting  Mayor  of  Mobile  Mr.  George  E.  Crawford  and  as  he  must 
be  in  close  touoh  with  Mr.  Clemens,  he  will  show  you  the 
letter  if  you  desire  to  read  it. 

Again  thanking  you  for  your  assistance  and  interest,  I  am 
Very  truly  yours, 

Hr.  tT.  M.  Clemens, 

Gen' 1  Secretary,  Chamber  of  Commerce, 
Mobile,  Ala. 

Bear  Sir: 

Referring  to  former  correspondence  with  Mr.  Thomas  A. 

Edison  on  the  subject  of  Alabama  coal,  Mr.  Edison  directs 
me  to  say  to  you  that  there  is  almost  universal  complaint 
from  those  interested  in  the  purchase  of  coal  about  the 
quality  of  it.  In  your  letter  of  February  8,  1918,  you 
enclosed  a  chemical  analysis  of  this  coal  in  comparison 
with  Pittsburgh  and  Virginia  ooals  v/hioh  was  very  favorable 
to  Alabama  ooal.  Bow  Mr.  Edison  thinks  that  you  should  know 
of  this  complaint  for  evidently  someone  has  been  selling  ooal 
of  an  inferior  quality  and  it  has  had  a  tendency  to  hurt  the 
city  of  Mobile  as  a  coal-purchase  market,  and  he  has  no  doubt 
that  the  Chamber  of  Commerce  would  wish  to  correct  this.  In 
one  of  Mr.  Edison's  first  letters  to  Acting  Mayor  Crawford  he 
said:  "It  is  very  important  that  the  quality  of  the  ooal  should 
be  the  best  grade,  so  the  Cubans  will  be  pleased  with  it  and 
help  build  up  a  trade."  In  a  letter  from  Mr.  Morgan,  American 
Consul  General  at  Havana,  he  says:  "I  took  up  the  matter  of  the 
importation  of  Alabama  ooal  with  all  the  railways  in  this  city, 
who  have  informed  me  that  they  would  not  by  ohoioe  use  this 
ooal,  as  it  was  not  suitable  for  their  purpose.  They  stated 
that  in  former  times  the  proposition  of  importing  this  ooal 
had  been  made  to  them  and  it  had  always  been  deolined."  This 
is  the  most  important  of  several  such  oomplaints  that  Mr. 

Edison  has  received  and  ho  feels  sure  that  the  City  of  Mobile, 
through  its  Chamber  of  Commerce,  would  wish  to  correct  this 
impression  where  the  faots  justify  it. 

In  oonolusion  I  would  say  that  Mr.  Edison  has  interested 
the  United  States  Shipping  Board  in  the  proposition  and  they 
will  probably  take  up  the  whole  matter  in  regard  to  transporting 
ooal  to  Cuba,  also  the  matter  of  return  oargoes  of  sugar  and 
molasses,  and  further  information  and  details  should  come  from 
them.  Mr.  Edison' s  interest  in  the  matter  has  been  solely  for 
the  good  of  the  cause  and  he  has  had  no  selfish  or  monetary 
interest  whatever.

This  folder  contains  correspondence  and  other  documents  relating  to 
Edison's  desire  to  develop  a  more  efficient  mechanism  for  feeding 
ammunition  to  machine  guns  by  using  hoppers  or  non-refillable  belts.  The 
correspondents  include  Edward  Craig  and  H.  W.  Morgan,  inventors  of  nail- 
handling  machines,  as  well  as  Brig.  Gen.  W.  S.  Peirce,  Lt.  Col.  Earl 
McFariane,  and  other  officers  of  the  Engineering  Division  of  the  Ordnance 
Dept.  Some  of  the  selected  items  pertain  to  Edison's  efforts  to  locate 
inventors  who  could  work  on  this  problem  and  to  obtain  guns  and  cartridges 
for  experimental  purposes.  Also  included  are  shipping  documents  relating  to 
Edison's  receipt  of  a  machine  gun  and  ammunition  for  use  at  Key  West,  along 
with  other  items  regarding  the  testing  of  Morgan's  hopper-type  ammunition 

Approximately  50  percent  of  the  documents  have  been  selected, 
including  all  items  detailing  Edison's  personal  involvement.  The  documents 
not  selected  include  routine  correspondence  dealing  with  requests  and 
shipments;  correspondence  between  Morgan  and  the  Engineering  Division; 
oversize  blueprints  sent  to  Edison  by  inventors;  and  a  report  on  a  test  of 
Morgan's  device  conducted  at  the  Springfield  Armory.

February  11,  1918. 

Mr.  Thomas  A.  Edison 

504  Havy  Annex  Bldg. , 

Washington,  D.  }C. 

Sir ; 

In  accordance  with  your  letter 
dated  August  20,  1917,  (CMG353.41/1)  in  which  you 
state  that  you  are  desirous  of  conducting  certain 
research  work  along  lines  of  materiel  used  in  the 
Army,  I  am  instructed  by  the  Acting  Chief  of  Ord¬ 
nance  to  request  that  you  consider  the  possibilities 
in  regard  to  Machine  Sun  Belts  as  mentioned  below. 

The  present  manner  of  supplying  am¬ 
munition  to  machine  guns  is  to  fill  long  belts  with 
ammunition  taken  from  clips  containing  five  cart¬ 
ridges  each, by  means  of  a  special  loading  machine, 
which  is  done  in  the  vicinity  of  the  place  where  the 
ammunition  is  expended.  The  cost  of  Ihe  clips  and  | 
packing,  maintenance  on  belts  and  boxes,  maintenance 
on  loading  machines,  and  maintenance  on  shipping 
cases  amountsto  about  0.7  cents  per  cartridge  used, 
or  about  #1.75  per  belt  of  250. 

It  is  thought  that  an  expendable  belt 
can  be  designed  which  will  be  made  of  a  paper  or  fib¬ 
rous  compound,  loaded  in  the  factory,  hermetically 
sealed  in  tin  cases,  and  forwarded  directly  to  the 
gun.  As  the  belts  are  required,  the  gunner  will 
mount  the  case  on  his  tripod,  open  it  and  proceed  to 
fire.  These  belts  will  be  used  but  once,  and  may  be 
of  any  substance  which  will  hold  the  cartridges  firm¬ 
ly  positioned  in  inclement  weather  for  several  hours. 

The  great  quantities  of  ammunition  belts 
and  boxes  which  are  constantly  being  purchased,  the 
confusion  necessitated  by  refilling  belts  in  the  for¬ 
ward  ammunition  dumps,  the  uselessness  of  machine  guns

February  25,  l'JIU. ‘dear  Mr.  Hdison, - 

Supplementing  my  telegram  of  Saturday  regarding  tho 
inventor  of  the  multiple  na il ing  machine  i’or  racking  boxos:- 
beinp  familiar  with  Patent  Office  proceedure  only  to  the 
extent  of  knowing  that  it  is  a  long  process  to  get  any 
accurate  information,  I  called  on  my  good  friend  and  cousin, 
j.;r.  Charles,  J.  O’lloill  of  the  firm  Pennie,  Goldsborough 
end  O'Heill,  patent  attorneys,  to  steer  me  in  tho  right 
direction.  He  was  kind  enough  to  leave  iiis  office  and  take 
me  by  short  cuts  to  tho  actual  file  of  all  the  patents 
bearing  on  nailing  machinery.  I’hero  were  hundreds  of  them 
in  several  classifications  including  every  device  from 
that  taking  in  rough  lumber  at  one  end  and  producing  straw¬ 
berry  baskets  at  the  other,  to  machines  which  would  drive 
only  one  nail  at  a  time  in  a  plank. 

with  lir.  O'lleill's  assistance  X  looked  ovor  tho  sketch¬ 
es  and  sent  you  the. names  of  inventors  who  had  perfected 
practicable  machines  which  suggested  a  possible  relation¬ 
ship.)  to  the  purpose  you  have  in  mind.  The  inventions  Oi 
Hlmer  C.  Iiorthrupp  of  Los  .'ngeles,  California,  seemed  to 
be  the  most  simple  and  effective.  Practically  all  of  his 
inventions  have’  been  immediately  assigned  to  the  i.utoma  oie 
Machine  Company  of  San  Francisco . 

In  the  process  of  running  down  the  subject  several 
■oatonts  relating  to  the  nailing  of  shoes  suggested  a  close 
resemblance,  or  at  least  a disability,  to  the  machine  gun 
'  orinoiple,  and  I  therefore  gave  you  _the_ names  also_ojL- — 
several  such  inventors .  /The  inventions  of  “frastus  Woodward  ' 
/Of  "Somerville  ,  Mass  ./"'al p e ar o d  to  me  to  be  the  most  inuer- 
(esting.  His  inventions  are  all  assigned  to  the  United  Snoe 
/  Machinery  Company.  Some  of  these  machines  drive  the  nails 
[  in  horse-shoe  order  in  heels,  while  others  show  e  mc.rvellous 
\  control  of  the  ncils  in  placing  them  simultaneously  in 
Various  positions  in  the  sole. 

Among  all  of  the  inventions  were,  of  course ,  a  great 
many  of  the  sporadic  type,  most  of  which  are  probably  not 
in  use.  X  took  as  an  index  to  the  practicability  of  the 
machines,-  and  ability  of  thoir  inventors,-  their  assignment 
to  producing  manufacturers. 


I  have  talked  v/ith  the  Washington .representative  of  the 
United  Shoe  Machinery  Company,  1.1,' .  Mr.  nk  L.  -eckham,  v.hora  I 
happen  to  know  very  v/ell  personally,  and  he  has  given  rae  a 
lot  of  interesting  information  concerning  the  machinery  they 
have  i'or  various  purposes.  He  states  that  all  of  the 
praoticahle  machinery  for  driving  nails,  eyelets,  buttons, 
etc.  in  connection  v/ith  shoes  is  owned  hy  the  United  Shoe 
Machinery  Company,  and  that  they  have  special  experts 
always  employed  in  development  and  improvements.  If  you 
care  to  have  the  purpose  of  the  inquiry  communicated  to  his 
home  office  Ilr.  1-eokham  states  that  the  Company  will  he  very 
glad  to  designate  their  most  capable  man  in  that  line  to 
confer  with  you  at  any  time  or  place  you  may  desire.

Dear  Sir: 

Eebruary  25,  1918. 

I  understand  you  are  one  of  the  inventors  of  the  modern 
nailing  machine  for  automatic  driving  of  nails  in  paoking 
boxes.  If  this  is  correct  I  want  to  state  that  the  Government 
is  desirous  of  improving  the  maohine  gun  in  connection  with 
the  belt  which  serves  to  hold  the  bullets  and  automatically 
feed  them  to  the  gun.  These  belts  are  expensive  and  cum¬ 
bersome.  They  have  asked  me  to  work  on  the  problem,  but  I  am 
so  busy  that  I  cannot  take  on  any  more  Government  work  and 
it  occurs  to  me  that  the  proper  person  to  work  it  out  is  the 
inventor  of  a  nailing  machine,  ily  idea  is  to  do  away  with 
the  belt  and  feed  the  bullets  from  a  hopper.  You  oan  probably 
see  one  of  these  guns  in  your  vicinity. 

If  you  are  willing  to  do  a  little  for  the  Government  let 
me  know.  If  after  you  have  seen  tho  gun  you  oan  make  drawings, 
I  will  have  the  feed  made  to  test  it  if  it  looks  feasible. 

Yours  very  truly,

Yotir  esteemed  favor  of  the  26th  reooived  and  X 
can  assure  you  that  T  will  ho  more  than  pleased  to 
assist  the  Government  in  designing  a  satisfactory

X  have  designed  and  constructed  quite  a  number 
of  hoppor  fed  machines  for  different  work  Imt  have 
never  had  any  experience  in  gun  work.  I  am  quite 
sure  hov/ever  that  I  can  design  and  construct  such  a 
device  if  I  oould  got  a  gun  to  work  upon  and  to  get 
all  of  the  available  information  as  to  just  what  has 
been  done  in  the  past  such  as  skotchos,  blue  prints 
and  all  patents  attempted  along  uhis\Line  with  critic¬ 
isms  sotting  forth  why  they  have  not  been  satisfactory 
together  with  suggestions  that  actital  praotise  has 
proven  would  be  desirable. 

Should  it  bo  impossible  to  send  this  gun,  would 
suggest  sending  drawings  or  patent  papers  covering 
the  same,  also  advise  nearest  point  where  one  of  these 
guns  may  be  seen.

Mr.  Thomas  A.  Edison, 

U.  S.  Naval  Station  ,

My  dear  Sir' : 

Your  favor  of  the  25th,  ult.  vas  duly  received,  and 
I  proceeded  at'  once  to  "  do  my  bit"  by  visiting  Fort  Benjamin 
Harrison;  and. looking  over  a  Colt  Machine  Cun  of  new  design 
with  bolt  feed. 

The  Eolt'  Feed  I  noticed  was  lacking  lie  positive  movement, 
due,  :as  I  bdliovo,  to  Its  tendency  to  wrinkle  and  buckle.  As  a 
means  to  overcome  this  defect,  1  sugges*  a  light,  steel-linked 
chain  •formed  into  a  narrow  bolt,  say-^/^.  uebes  wide,  to  b,  carried 
by  the  positive  movement  of  Snrookut  Wheels,  thi  power  b,iug 
supplied  by  th:  operation  of  firing  the  gun.  The . links  of . Ino 
chain  should  form  pockets  which  would  carry  the  cartridges  forward 
to  the  firing  point. 

I  respectfully  submit  to  you  for  consideration,  two  sk<rl ohos 
of  Hopper  Feeds,  showing  the  manner  of  feeding  the  cartridges 
to  th.  •■  gun .  •  I  prefer  the  ov»  rorrosi.ntir.g  feed  by  two  hoppers. 
In  that  sketch, the  right  r.  ido  hop;  ..  r  will  always  bo  supplemented 
by  th-  hopper  on  n  -  l  ift, which  is  ready  to  sup;  iy  cartridges 
to  an.''  Vac'at  t  pocket  which  may.  come  under  It,  thus’ ‘assuring  a 
ro:  1  t  pious  supply  of  ammunition  o  ’■  h  •  gun.  . 

Th.  hep-;  era  ,  1  believe,  can  b-  k-it  filled  by  one  man, 
and  a  continuous  fir;  b:  kept  u;  if  desired.  Th-  chains  and  mech¬ 
anism  hr  durable.  The  chain  must,  of  course, bo  as.  light  as  poor-, 
iblo  to  giv-.-  -he  necessary  strength.  This  method  of  feeding 
eliminates  the.  labor  and  time  roiuir-d  to  remove  t.-.o  empty  bolt, 

and  to  fill  the  belt  and  replace  it  .  . 

!  'am  unable  to  show  perspective.,  but  1  trust  my  rough 
with  tho  notations  will  convoy  my  idea.

enlisted  the  interest  of  two  competent  inventors  in  this  mat¬ 
ter  ^  which  action  on  your  part  is  greatly  appreciated. 

3.  In  order  to  thoroughly  familiarise  these  men  with  the 
requirements  whioh  are  to  bo  mot,  it  is  felt  that  if  possible  they 
should  arrange  to  visit  the  Springfield  Armory  at  Springfield,  llass., 
at  which  place  there  is  an  Experimental  Department  woll  supplied 
with  machine  guns  of  all  makes,  in  charge  of  officers  expert  in  the 
operation  and  handling  of  machine  guns.  After  their  visit  to  the 
Armory  they  can  be  .  supplied  with  the  two  guns  with  which  they  de¬

Dear  Sir: 

I  am  enolosing  with  this  a  blue  print  of  another 
type  of  machine  gun  hopper.  I  tahe  it  for  granted 
that  the  other  prints  I  submitted  in  February  are  not 
quite  satisfactory,  however  I  am  positive  if  can 
get  a  true  lino  on  the  rigid  requirements  of  the  U.S. 
standard  machine  gun  that  I  can  design  a  satisfactory 
hopper  feeder. 

One  of  the  best  features  of  this  new  deviae  is 
being  able  to  turn  the  shell  carrier  by  hand  thereby 
filling  up  the  entire  ring  with  shells  before  starting 
the  gun.  This  would  give  at  least  50  shots  and  would 
not  fail  to  operate.  The  shells  are  plaoed  in  the  oentei 
of  the  housing  thru  the  rear. 

The  shell  feeding  pawl  engages  the  end  of  the  shells 
forcing  it  over  into  position  carrying  the  shell  ring  with 
it,  the  carrier  ring  rides  upon  the  shells  as  they  pro¬ 
ject  slightly  below  the  inBide  diameter. 

Should  the  above  appear  impractical,  I  would  be 
pleased  to  have  it  criticised,  also  any  suggestions  you 
may  have  to  offer. 

As  stated  in  my  former  letter  if  I  could  get 
for  a  short  time,  or  a  full  size  drawing  of  one, 
sure  I  could  develop  a  satisfactory  feeder.

Dear  Sir:- 

I  have  been  out  of  town  for  a  day  or  two  and 
just  received  your  favor  of  the  fourth. 

I  have  been  making  some  sketches  and  trying 
to  figure  out  what  might  be  a  solution  of  the 
requirements  on  the  machine  gun,  but  it  would  be 
a  very  great  help,  as  Ur.  Edison  suggests,  if  I 
had  a  machine  gun  here  to  experiment  with.  X 
have  examined  one  but  had  to  go  to  Hew  York  to 
do  so. 

I  can  assure  you  that  I  will'uso  every  effort 

to  do  anything  I  can  to  help  this  matter  along. 

Very  truly  yours.

I  shall  he  very  glad  to  receive  the  machine  gun, 
with  belts,  ammunition,  etc.  Will  do  everything 
I  can  to  try  and  help  in  the  matter  of  which  you  speak. 
I  have  been  at  work  on  this  but  as  yet  have  not  figured 
out  what  might  seem  to  be  a  suitable  device.  However, 
will  keep  at  it  and  use  every  effort  to  bring  something 

You  may  ship  the  machine  gun  to  H.  Vf.  Morgan,  c/o

Dear  Sir:- 

Your  favor  of  the  Oth  instant  to  Hr.  lid  icon

to  have  several  thousand  cartridges.  He  fools  suro 
that  you  can  rot- rid  of  tho  bolt  and  feod  cartridges 
from  a  hoppor. 

Yours  vory  truly. 

Assistant  to  iir.  Edison. 


itef  erring  to  your  soveral  communications  on  this 
subject,  after  experimenting  on  several  different  lines, 

I  have  succeeded  in  making  a  machanical  feeding  device 
to  feed  cartridges  into  the  gun  from  the  original  cachin' 
box,  as  follows. 

1’his  feeding  device  is  placed  in  position  on  tne 
tripod,  in  the  grooves  Provided  for  installing  the  belt 
feed  box.  It  is  not  attached  to  the  gun  in  any  other  wa 
so  it  dees  not  interfere  with  the  same  gun  feeding  belt 
cartridges,  if  desired. 

The  power  for  operating  the  feeding  device  is  obf 

near  the  end  of  the  barrel  of  the  gun,  whi 
hy  the  explosion  and  returns  by  means  of  * 


this  arm  returns  it  trips  a  little  pawl,  which  operates  the 
feeding  device. 

The  box  holding  the  cartridges  is  an  ordinary  Pine 
box,  -  made  special,  however,  for  the  purpose.  It  is  intended 
that  this  box  be  filled  at  the  cartridge  factory  and  it  is 
then  ready  for  the  gun. 

It  is  placed  on  the  feeding  device  and  the  gun  fired 
in  the  ordinary  manner.  7?hen  the  box  is  empty  it  is  dis¬ 
carded  and  another  one  put  in  place.  It  takes  about  eight 
seconds  to  discard  an  empty  box  and  olace  a  filled  one  in 

The  box  which  I  have  made  contains  one  hundred  .cart¬ 
ridges;  it  can  be  made  larger  or  smaller,  if  desired. 

This  device  feeds  the  cartridges  successfully  to  the 
gun  in  whatever  position  of  adjustment  the  gun  may  be. 

I  have  tested  the  gun  by  firing  the  cartridges  from  the 

3  device  and  insofar  as  I  can  see  it  does  the  work.^^^p 

box  Ufa  thi 

As  I  am  not  familiar,  however,  with  machine 

practice,  I  l) 

do  not  know  whether  this  device  is  suitable  or  not. 

Please  advise  me  as  to  the  next  step. 

I  am  sending  a  copy  of  this  letter  to  Ur.  Sari  McFarland , 
lieut.  Col.  H.  A.  War  Department,  Office  of  Chief  of

Orange  ,  Hew  Jersey.  ; 

%  dear  Ur.  Edison: 

I  am  in  receipt  of  your  favor  of  the  third.  ..'ill  he 
very  glad  to  he  nr  from  you  or  from  Washington  in  regard 
to  the  feeding  device  for  cartridges  in  machine  gun  which 
I  have  been  experimenting  with. 

I  sent  a  copy  of  the  letter  which  I  wrote  you.  on 
August  25th  to  Ur.  Earl  1.1c  Ear  land,  Lieut.  Col.  ii.  A.  far 
Department,  Office  of  Chief  of  Ordnance,  Engineering  Bnreau, 
451  Pennsylvania  Ave. ,  7/a.shington ,  D.C.,  as  he  stated  there 
was  an  urgent  need  for  such  a  device  when  he  wrote  rr.o  that;  he 
had  sent  me  the  gun  to  work  on.  '.'is  have  not  heard  from 
Mr.  i.IcEarland  and  do  not  know  that  ho  is  the  party  to  hear 
from,  hut  inasmuch  as  he  stated  the  urgent  need  of  the  Govern¬ 
ment  for  such  a  device,  we  sent  him  a  copy. 

X  have  made  several  tests  and,  so  far  as  1  can  see,  the 
feeding  device  works  correctly.  The  boxes  that  I  had  made 
to  hold  the  cartridges  contain  one  hundred  each  hut,  as  stated 




Two.  September  15,  1918. 

in  my  previous  letter,  the  device  could  he  made  to  handle 
more  or  less.  Hot  having  a  large  supply  of  cartridges, 

I  would  put  twenty,  thirty  or  forty  in  a  box,  fire  them 
out  and  change  the  box  and  the  feeding  device  seems  to 
handle  them  correctly.  I  believe  it  is  a  considerable 
-advantage  from  fact  that  the  box  of  cartridges  packed 
at  the  cartridge  factory  is  the  one  put  into  the  device, 
without  any  change  or  manipulation. 

X  wrote  the  Springfield  Armory  a  day  or  two  ago  and 
asked  if  they  would  send  us  five  or  six  hundred  cartridges, 
giving  the  number  of  the  order  on  which  the  previous  five 
hundred  were  sent.  I  wanted  these  to  have  on  hand  in 
case  information  came  from  you  that  officials  would  come 
here  to  see  the  device  tested. 

In  answer  to  this  letter  I  received  the  following 

"Reference  your  letter  to  Springfield  Armory, 
dated  September  seventh,  requesting  shipment  of 
cartridges,  this  transaction  will  have  to  be 
either  a  sale  to  your  Company  or  an  issue  to 
Inspector  of  Ordnance  at  your  plant.  .'lire 
this  office  whether  you  wish  it  to  be  a  sale  or 
an  issue." 

-his  telegram  was  sent  from  7/ashington  and  signed 
"Supply  Division,  34188,  Army  Ordnance". 

I  do  not  care  whether  they  send  the  cartridges  to  me 
as  a  sale  or  an  issue,  but  as  there  is  no  Inspector  of 
Ordnance  at  our  place  I  am. a  little  at  a  loss  to  know  just 
what  to  do.  I  enclose  a  copy  of  a  letter  which  I  have  sent 
in  reply  to  their  telegram. 

My  anxiety  is  that  if  I  can  do  anything  to  help  win  the

X  hardly  know  how  to  answer  this  telegram  as  thoro  iB

I  wouia  explain  that  at  the  request  of  Ur.  f ho mas  A.

The  gun  was  received  on  June  Oth,  but  the  10,000 
rounds  of  small  arms  ammunition  was  not  included.  later, 
on  June  8th,  I  wrote  to  Springfield,  stating  that  no 
ammunition  was  roooivod  with  whioh  to  moke  a  test.  I 
askod  for  five  hundred  rounds,  whioh  were  sent  mo.  1

1  am  perfectly  willing  to  pay  for  them*  ns  this  would 
be  a  very  small  amount  oomparod  to  what  X  havo  already

"  deferring  to  your  letter  of  October  <28tA  t,t  ,..  c  ,<f*s  't 
(BS  400.111/1070)  I  am  instructed  by  the  Chie’fVi  (_ltf  ' 

Ordnance  to  inform  you  that  the  report  on  the  result^' 
of  the  tests  on  your  mechanical  feeding  device  for  t  (t  (  {,t 
machine  guns,  which  was  conducted  at  the  Springfield 1  ' 
Armory,  has  just  been  received  by  this  office.  /• 

Enclosed  you  will  find  a  copy  of  this  report.  f 

-ou  will  note  that  the  principal  difficultie: 
encountered  were  the  failure  to  feed  when  the  gun 
was  fired  at  an  angle,  the  weight  of  the  device  a: 
the  fact  that  it  Y/auld  have  to  be  redesigned  for  i 
with  the  Browning  gun.  (The  report  states  that  i 
greater  elevation  than  sixty  degrees  it  would  not 
satisfactorily.' ) 

As  you  nny  know,  ther6  has  recently  been  put 
into  manufacture  a  form  of  expendable  ammunition 
and  box,  which  reduces  the  weight  of  thi'S  equipme: 
and  adds  nothing  to  the  weight  of  the  gun. 

The  Chief  of  Ordnance  directs  rno  to  thank  yo 
for  having  presented  this  device  for  con3ideratio 
and  also  for  your  patriotic  efforts. 

Hovomber  1U,  1918. 

Owing  to  tho  face  that  you  havo  boon  put  to 
oons iderable  expense  in  developing  your  device,  this 
Office  feels  that  you  are  entitled  to  proper  com¬ 
pensation  and  would  be  glad  to  havo  you  submit  a 
bill.  " 

To  this  letter  I  replied: 

•'  I  am  in  receipt  of  your  favor  of  the  4tli  also 
the  report  on  the  machine  gun  Reding  device  which 
I  submitted  to  the  Department  for  the  teot.  X  wish 
to  thank  you  for  same. 

I  realise  that  the  device  was  heavier  than  need 
be  if  made  in  a  manufactured  way.  ..’ouid  also  state 
that,  by  changing  the  method  of  applying  the  operatior 1, 
it  could  be  fitted  to  the  Browning  Gun.  dote,  also, 
that  you  have  succeeded  in  obtaining  an  expendable 
ammunition  belt  and  box. 

In  regard  to  the  expense,  I  will  state  that  I 
have  no  bill  to  present  to  the  Department.  -t  the 
of  hr.  Thomas  A.  iidison  to  see  if  a  device 
could  be  made  without  a  belt,  I  undertook  to  develop 
this  device.  I  am  pleased  to  have  made  the  experiment, 
and  the  only  compensation  a  work  01  thskf 
the  satisfaction  of  knowing  that  I  have  tried  to 
my  Country  in  any  way  that  1  can. 

I  am  also'  in  receipt  of  a  letter  today  from  the  Oliief  of 
fdnance,  reading  as  follows: 

„  wofarriE  to  your  letter  of  Uovembor  8th,  I  am 
instructed  by  the  Chief  of  Ordna: 

device  ^-is  office  also  desires  to  thank  you  for 
having  done  this  work  without  thought  or  aOoiic  ior 
recompense . 11 

I  presume ,  as  the  war  is  now 
led  of  further  work  in  this  line. 
i  attempt  to  serve  the  Country.

I  am  glad  to  havo  made

My  dear  Mr.  Morgans 

I  am  much  interested  in  the 
contents  of  your  letter  of  the  18th  instant,  from 
which  I  derived  my  first  information  of  the  results 
of  the  test.  Although  I  specifically  requested 
the  Department  to  keep  me  informed  of  the  results, 

I  have  not  yet  heard  from  them. 

Dot  me  thank  you  very  much  for  the  full 
information  you  have  sent  me.  Your  action  through¬ 
out  the  entire  transaction  has  been  very  fine.  If 
you  take  much  interest  in  this  improved  device,  you 
might  put  it  on  a  business  basis  by  filing  an  applica¬ 
tion  for  patent  and  continuing  to  perfect  the  device. 
These  Ordnance  people  are  incapable  in  this  respect. 
All  advances  are  made  by  outsiders. 

I  think  your  method  i3  the  only  proper  one, 
as  belts,  cloth  or  paper,  are  fundamentally  unsatis¬ 
factory  and  probably  always  will  be. 

Yours  very  truly.
